Recently, incremental sheet metal forming (ISMF) process as one of the new methods in rapid prototyping collection has been considered by researchers. This process is based on a defined path in CNC controller and applies ...

Abstract: In this paper, a new population-based search called the Bees Algorithm (BA) is presented to estimate the time-dependent heat transfer coefficient and the corresponding heat flux at the boundaries of a two-dimensional ...

Sliding mode control (SMC) is a powerful approach to solve the tracking problem for   dynamical systems with uncertainties. However, the traditional SMCs introduce actuator chattering phenomenon which performs a desirable ...

Abstract: A time domain semi-analytical solution to study thermoelastic creep behavior of  functionally graded rotating axisymmetric disks with variable thickness is presented. The rate type governing differential equations ...

Fabrication of ultrafine grained materials by imposing severe plastic deformation for improvement of mechanical and physical properties of metals has been the focus of many researches over the past few years. In this ...

Abstract: The lifetime of a cutting tool is an important and determinant parameter for evaluating its performance. The amount of tool abrasion affects seriously dimensions and surface quality of the working piece so that ...

Abstract: Since the field of micro electromechanical systems (MEMS) continues to grow, the flow in micro devices have become an area that receives a significant attention. The microscopic flows are usually characterized ...

Conjugated polymer actuators can be employed to achieve micro and nano scale precision, and have a wide range of applications including biomimetic robots, and biomedical devices. In comparison to robotic joints, they do ...
