Self piercing riveted joint

Submitted by manibijju on

Hello,

I am working on Self piercing riveted joints and trying to simulate using Lsdyna,iam using piecewise linear plastic material model. The rivet is not able to pierce into the sheets, insted it is compressing the elements and elongating them. 4-noded shell elements where used. i want to know how will the elements get broken up or removed from the path of the rivet, I have used one way erode contact card but it was of no use. If any one can suggest  me how the approch should be i would be a great help.

Software/codes for atomistic/continuum coupling multiscale materials modeling

Submitted by Shuozhi Xu on

There exist some software/codes for atomistic/continuum coupling multiscale materials modeling methods (in alphabetical order):

1. AtC, atomistic-to-continuum coupling, included in LAMMPS

2. BDM, bridging domain method, included in LibMultiScale

3. MMM, multiresolution multiscale mechanics method

Challenges in the finite element analysis of tire design using abaqus

Submitted by American Engin… on

Finite Element Analysis of Vehicle and Tire has become a very important aspect of a tire design and failure analysis to most Tire companies. Tire modeling with ABAQUS is a very complicated process involving complex materials like hyperelastic rubber and textile reinforcements, large model size, prolonged simulation time and various convergence issues. This white paper intends to help in understanding the challenges in tire analysis and several tips and tricks that makes a difference in the quality of the results and processing time.

Question on history of mechanics

Submitted by P Hartley on

A question for those interested in the history of mechanics. We have Hooke's law for 2D stress-strain and a generalised Hooke's law for 3D stress states. Maybe I have missed something in my reading of history, but since it appears that it was Thomas Young and not Hooke who related stress and strain (Hooke looked only at force - displacement), why don't we use Young's law or a generalised Young's law?

How to define pressure direction in ANSYS

Submitted by ladanyi on

Hi everyone,

 

I am quite new in ANSYS Classic and now I had to realize a serious problem. After building a steel frame from beam4 elements I tried to define pressure on beams.

I can not find the direction of the pressure. It could work in or perpendicular to the plane of the frame (for example).

Could anybody help me, how to define the direction?
