Numerical Simulation for Laser Processing

simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

Numerical simulation of laser beam welding of Ti6Al4V sheet

This paper was aimed to report the 3D finite element analysis simulation of laser welding process of Ti6Al4V 1.7 mm sheets in butt joint in order to predict the temperature distribution, hardness, and weld geometry. The butt-joint welds were made using CO2 laser with the maximum power of 2.2 kW in the continuous wave mode. A part of the experimental work was carried out to verify the weld geome...

Numerical Simulation of Pulsed Laser Bending

The aim of this work is to develop an efficient method for computing pulsed laser bending. During pulsed laser bending, thousands of laser pulses are irradiated onto the target. Simulations of the thermomechanical effect and bending resulted from all the laser pulses would exceed the current computational capability. The method developed in this work requires only several laser pulses to be cal...

Numerical Simulation of Infrared Laser Probing Techniques

Exploiting the dependence of the refractive index on carrier concentration and temperature, various infrared laser probing techniques enable the experimental analysis of the carrier and heat flow distributions in the interior of semiconductor devices. In this work we present a complete numerical simulation sequence for the whole measurement process. It includes the electrothermal device simulat...
