Laser bending is an advanced process in sheet metal forming in which a laser heat source is used to shape the metal sheet. In this paper, temperature distribution in a mild steel sheet metal is investigated numerically and experimentally. Laser heat source is applied through curved paths in square sheet metal parts. Finite element (FE) simulation is performed with the ABAQUS/CAE standard softwa...

A literature review on methods to consider mechanical behaviour of cast aluminium alloys in finite element method (FEM) simulations of cast aluminium components has been performed. The mechanical behaviour is related to several microstructural parameters achieved during the casting process. Three different methods to consider these microstructural parameters are introduced. One method predicts ...

Abstract Heat accumulation during laser powder bed fusion (LPBF) of metallic build parts can adversely affect their microstructure and mechanical properties. To study the heat 316L steel based manufactured by LPBF, a finite element method (FEM) numerical is carried out. For investigation, computationally efficient FEM model, where whole layer simultaneously exposed to source, used. The simulati...

This report presents a voxel-based biomechanical model for muscle deformation using nite element method (FEM) and volume graphics. Hierarchical voxel meshes are reconstructed from ltered segmented muscle images followed by FEM simulation and volume rendering. Physiological muscle force is considered and linear elastic muscle models for both static and dynamic cases are simulated by FEM. Voxel-b...

Microsystem technology is a highly interdisciplinary area. Therefore, a combination of different CAD methods and tools is necessary for supporting microsystem design. Process and device simulation are basic CAD methods but more and more higher levels of abstraction need to be applied in order to analyze microsystems adequately. This paper summarizes several modeling and simulation strategies fo...

Introduction The force production of a muscle is influenced by numerous properties, the probability of links between actin and myosin resulting in a velocity-force relation – the degree of overlap between actin and myosin resulting in a length-force relation – and the activation behavior of a single muscle fiber as well as the activation of different motor units resulting in an activation funct...

Introduction: Photothermal therapy using gold nanoshells is one of cancer therapy methods. Gold nanoshells generally consist of a silica core and a thin gold shell. Fe3O4@Au core-shell can be used for magnetic targeted therapy. The objective of this study was investigation of the photothermal effects of magnetically targeted Fe3O4@Au NPs and NIR laser irradiation on model of me...
