thermal analysis of welds using ANSYS

Submitted by sandyxlr123 on

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.

Fracture of Rubber. Lecture 2

Fracture mechanics without invoking any field theory. In Lecture 1 on Fracture of Rubber, we considered the extension of a crack in an elastic body subject to a load. Following Rivlin and Thomas (1953), we regarded the elastic energy stored in the body as a function of two independent variables: the displacement of the load, and the area of the crack. The partial derivative of the elastic energy with respect to the area of the crack defined the energy release rate.

damage mechanics

Hello,

 

I seek help from the forum regarding the following. Because I am very new to mechanics.

I have a continuum damage mechanics model with me. I have set up a problem of a typical three point bending test on a notched beam. The notch in the center of the specimen and extends from the bottom face up to the middle of the thickness. It is a plane stress problem. Now I want to simulate load-displacement curve obtained from the experiment (s).

Abaqus Quistio

Submitted by ehsan_atefi on

I am working on Dental Implants and i want to define interaction in abaqus between an implant and the bone surrunding it. I am using Abaqus CAE to do it and i want to define frictional interaction with penalty method but I have problem with the penetration of implant in the bone. I've tried all the possible contact definitions such as surface to surface or node to surface. Sometimes Abaqus gives me some incredible answers for example pulling out the implant!!!! Please help me with this problem. Thank you....

Need an example of wave propagation in a plate using abaqus

Thin plate

Hi every body,I'm a senior student in mechanics and really I need an
example of wave propagation in a thin plate to conduct my project. At
now,main problem for me is how to apply load to get answers with
obvious wave propagtion contour plot without any thing more in just one
refelection.

Thanks in advance,

Hadishah
