How to model a polypropylene Infrared Weld Seam for tensile testing
I am trying to use Ansys workbench to model a weld from an infrared welder so that I can conduct a tensile FEA test on it. I have the SolidWorks files of the seam, but I am unsure how to actually ...

How to match ANSYS stress calculations with force and moment reaction values
Given a simple cantilever beam with an axial and transverse load, I look at both the axial force and the bending moments on a surface through the middle of the beam. The issue is, when I calculate the ...

SolidWorks assembly with contacts imported into Ansys Workbench 2022
Why does Ansys not recognize a split surface created in SolidWorks, a cylindrical surface, where each half contacts a different part in the assembly and have different types of contact, and imported ...

What's the issue here with Rigit Dynamics?
I was trying to simulate my walking robot in ANSYS rigid dynamics. I made it work before with another version of the robot (Different body shape but exact same walking mechanism) and it worked. But ...

What constraints would I use to model a flying saucer?
Let's say there is a disk suspended in space spinning at high speeds. I want to determine the eq. stress profile from centrifugal stresses. In Ansys, I've already applied a rotational velocity. ...

Creep FEA analysis (failure modes)
Hi I recently came across failure modes like creep, ratcheting and fast fracture. If I wanted to model these in Ansys mechanical, would it be correct to say that if, for example I modelled creep, I ...

Parametrizing Stress Strain Curves for Ductile Materials with Ramberg-Osgood at Elevated Temperatures
Question: Is there a way to determine the uniform elongation (i.e., strain at tensile ultimate strength $F_{tu}$) when given the tensile yield and ultimate strengths, elastic modulus, and total ...

Uniform Direction for Line Directions
Despite several similar questions and my efforts, there is still no solution so far. Presently, ANSYS gives Directions to Lines on its own which are flipped even for two collinear lines. As a results ...

Setting direction vectors for Lines in ANSYS APDL
I am using beam elements to mesh lines with "pre-meshed" shell areas. Problem is that the ANSYS sets Line Direction vectors on its own. This results in Cross sections assignment flipped from ...
