thermal analysis of welds using ANSYS
HI EVERYBODY,
I HAVE BEEN TRYING TO DO THE THERMAL ANALYSIS OF WELDS COUPLED WITH THE MECHANICAL ANALYSIS TO DETERMINE THE RESIDUAL STRESSES RESULTING IN IT.I HAVE COUPLE OF DOUBTS IN THIS CONCERN-
1.THERE IS THE USE OF FILLER MATERIAL-I KNOW ELEMENT DEATH AND BIRTH METHOD IS TO BE USED BEHIND IT,BUT DONT KNOW HOW TO APPLY IT
2.SECONDLY THE MOVING HEAT SOURCE-WHETHER ANY GAUSSIAN DISTRIBUTION IS TO APPLIED AND HOW TO GET A MOVING HEAT SOURCE.
3.WHETHER ALL CONVECTIVE AND RADIATIVE BOUNDARY CONDITIONS HAVE TO BE APPLIED ON OTHER SURFACES SIMULTANEOUSLY.
