Transient Dynamic Analysis of Clamped Clamped Laminated Cylindrical Shell

Transient Dynamic Laminated Shell

Dear friends,

I am trying to find thife transient dynamics response of clamped clamped laminated cylindrical shell subjected to Radial impulsive load. I am getting very irregular response using Newmark Integration scheme. But, using HHT-alpha method, high frequency noise from the response gets removed, but damping is intrdoced (Numerical Damping). Although i have not introduced and damping in my model. How to overcome this problem.

I need help in this regard.

Regards

Post doc: Buckling in soft polymeric materials

Submitted by velankar on
job

A post-doctoral position is available in the lab of Sachin Velankar at the University of Pittsburgh to examine buckling instabilities in soft polymeric materials. The project is experimental, and therefore some past experimental experience with polymers is desirable. However this project requires a thorough understanding of elastic instabilities, and therefore a comprehensive grasp of mechanics is absolutely essential  – indeed more important than past experimental expertise.

rubber elasticity

Hi I need a help if anyone can solve my problem please help me out. I want to use the output file of the result as a input file in ABAQUS i.e, if a apply tensile load to a model it will elongate and I need the elongated model as a input file for carrying out the next step. If anyone can pl send me the .jnl file or .inp or .cae file. I am using ABAQUS/STANDARD VERSION 6.8

Forensics: residual stress of fractured part

fracture mechanics
residual stress

I’ll present this below without the answer, in case you want to enjoy a little brain teaser. It is a solid and experimental mechanics problem that, while not terribly practical, I found very interesting:

A part fractures cleanly in two by brittle fracture (no plasticity) under the action of residual and applied stresses. You only have the broken part in front of you, no prior information.

 What were the original residual stresses on the fracture plane?
