Book Description :

This is the first single volume monograph that systematically summarizes the recent progress in using non-Fourier heat conduction theories to deal with the multiphysical behaviour of smart materials and structures. The book contains six chapters and starts with a brief introduction to Fourier and non-Fourier heat conduction theories. Non-Fourier heat conduction theories include Cattaneo-Vernotte, dual-phase-lag (DPL), three-phase-lag (TPL), fractional phase-lag, and nonlocal phase-lag heat theories. Then, the fundamentals of thermal wave characteristics are introduced through reviewing the methods for solving non-Fourier heat conduction theories and by presenting transient heat transport in representative homogeneous and advanced heterogeneous materials. The book provides the fundamentals of smart materials and structures, including the background, application, and governing equations. In particular, functionally-graded smart structures made of piezoelectric, piezomagnetic, and magnetoelectroelastic materials are introduced as they represent the recent development in the industry. A series of uncoupled thermal stress analyses on one-dimensional structures are also included. The volume ends with coupled thermal stress analyses of one-dimensional homogenous and heterogeneous smart piezoelectric structures considering different coupled thermopiezoelectric theories. Last but not least, fracture behavior of smart structures under thermal disturbance is investigated and the authors propose directions for future research on the topic of multiphysical analysis of smart materials.

Book Description :

Nanosensors for Smart Manufacturing provides information on the fundamental design concepts and emerging applications of nanosensors in smart manufacturing processes. In smart production, if the products and machines are integrated, embedded, or equipped with sensors, the system can immediately collect the current operating parameters, predict the product quality, and then feed back the optimal parameters to machines in the production line. In this regard, smart sensors and their wireless networks are important components of smart manufacturing. Nanomaterials-based sensors (nanosensors) offer several advantages over their microscale counterparts, including lower power consumption, fast response time, high sensitivity, lower concentration of analytes, and smaller interaction distance between sensors and products. With the support of artificial intelligence (AI) tools such as fuzzy logic, genetic algorithms, neural networks, and ambient intelligence, sensor systems have become smarter. This is an important reference source for materials scientists and engineers who want to learn more about how nanoscale sensors can enhance smart manufacturing techniques and processes. Outlines the smart nanosensor classes used in manufacturing applications Shows how nanosensors are being used to make more efficient manufacturing systems Assesses the major obstacles to designing nanosensor-based manufacturing systems at an industrial scale

Book Description :

Robotics is an area of engineering and science that encompasses electronics, mechanical engineering, and computer science, among other disciplines. This branch is concerned with the design, building, and use of robots, as well as sensory feedback and data processing. In the coming years, these are some of the technologies that will replace humans and human activities. These robots are designed to be utilised for a variety of tasks, however they are currently being used in sensitive environments such as bomb detection and deactivation. Robots can take on any shape, although many of them have a human-like look. The robots that have taken on a human-like appearance are expected to move, speak, and think like humans. Robotics is the engineering discipline that deals with the conception, design, operation, and manufacture of robots. Issac Asimov, a science fiction novelist, claimed to be the first to name robotics in a short tale written in the 1940s. Issac proposed three principles for guiding these types of robotic robots in that scenario. Issac's three rules of Robotics were later named after these three ideas. The following are the three laws: Humans will never be harmed by robots. With the exception of breaking law one, robots will follow human commands. Without breaking any other restrictions, robots will defend themselves. Characteristics The following are some of the properties of robots: Robots have a physical body that they can move around in. They are maintained in place by their body's structure and moved by their mechanical components. Robots will be nothing more than a software programme if they don't have an appearance. On-board control unit is another name for the brain in robots. This robot receives data and then sends commands as an output. Otherwise, the robot will just be a remote-controlled machine without this control device. Sensors: These sensors are used in robots to collect data from the outside world and deliver it to the Brain. These sensors, in essence, have circuits in them that produce voltage. Actuators are the robots that move and the pieces that move with the help of these robots. Motors, pumps, and compressors are examples of actuators. These actuators are told when and how to respond or move by the brain. Robots can only work or respond to instructions that are given to them in the form of a programme. These programmes merely inform the brain when to do certain things, such as move or make sounds. These programmes only instruct the robot on how to make judgments based on sensor data. The robot's behaviour is determined by the programme that was created for it. When the robot starts moving, it's easy to identify what kind of programme it's running. The Different Types of Robots The following are some examples of robots: Articulated: This robot's distinguishing feature is its rotational joints, which range in number from two to ten or more. The rotary joint is attached to the arm, and each joint is known as an axis, which allows for a variety of movements. Cartesian robots are also referred to as gantry robots. The Cartesian coordinate system, i.e. x, y, and z, is used in these three joints. Wrists are fitted to these robots to give rotatory mobility. Cylindrical robots contain at least one rotatory and one prismatic joint for connecting the links. Rotatory joints are used to rotate along an axis, while prismatic joints offer linear motion. Spherical robots are sometimes known as polar robots. The arm has a twisting joint that connects it to the base, as well as two rotatory joints and one linear joint. Scara: Assembly robots are the most common use for these robots. Its arm is shaped like a cylinder. It features two parallel joints that give compliance in a single plane. Delta: These robots have a spider-like structure to them. They're made up of joint parallelograms joined by a shared basis. In a dome-shaped work area, the parallelogram moves. They're mostly used in the food and electronics industries. Robots' scope and limitations: Advanced machines are robots that are trained to make decisions on their own and are utilised to do advanced tasks. When designing a robot, the most crucial considerations are what function the robot will perform and what the robot's constraints are. Each robot has a fundamental level of complexity, with each level having a scope that restricts the functions that may be done. The number of limbs, actuators, and sensors used in basic robots determines their complexity, whereas the number of microprocessors and microcontrollers used in sophisticated robots determines their complexity. As with any increase,

Book Description :

A quarter century period of the 3D printing technology development affords ground for speaking about new realities or the formation of a new technological system of digital manufacture and partnership. The up-to-date 3D printing is at the top of its own overrated expectations. So the development of scalable, high-speed methods of the material 3D printing aimed to increase the productivity and operating volume of the 3D printing machines requires new original decisions. It is necessary to study the 3D printing applicability for manufacturing of the materials with multilevel hierarchical functionality on nano-, micro- and meso-scales that can find applications for medical, aerospace and/or automotive industries. Some of the above-mentioned problems and new trends are considered in this book.
