Hello,
i am an undergraduate mechanical engineering student & currently working on a project which involves finite element modeling & torsion analysis of a composite material based thin cylindrical tube.
As a part of coursework, i am well familiar with the Classical lamination theory (CLT) of macromechanics of laminates.
The problems i am facing in initiating my work are :
Hello Everyone,
I have a question and I really appreciate any comment:
I want to know which method(steps) i will prefer to find frequency of cracked and uncracked beam.
Please give me suggestion about this problem quickly.
Thanks in advance.

Hello
I am doing a Modal analysis on a structure made up of 3D-Beam4, Mass21 and Shear panel 28. To be more clear, the structure looks like a cube made up of Beam element on all 12 edges with Mass21 element at all corners of the cube and also with shells (shear panel 28) at all six faces of the cube.
I first constructed the beam structure with keypoints and lines, then i added the point masses and meshed them, then i created the shell element using Modelling-create-area and meshed it. Finally i merged them using "NUMMRG, ALL" in the command field.
Hello everyone,
I build a 3D model in abaqus to simulate nanoindentation.The job finished successfully, but the problem is when I run the odb file for output there is no stress distribution in the specimen around the tip.Its just like a knife poking a piece of butter.There is no stress distribution!!I did the nanoindentation simulation in 2D .It was ok then.But for 3D I am facing this problem.Anyone can help?
The boundary condition I used is:
For making the specimen fixed :u1=u2=u3=ur1=ur2=ur3=0
