I am designing a diaphragm for shock tube, I need formulation to calculate the thickness of the diaphragm for rupture pressure, I intend to use thin aluminium foil as a diaphragm. Can I use thin-wall theory? σ=pr/t

Hi all.

I'm Filippo, a new entry on imechenica community. I'm looking for a simple UEL code for Quad_2D-plane stress or plain strain.

Here's someone that can suggests manual or similar. 

I'm grateful in advance. 

 hi guys

am Mr.sam doning phd in mechanical engineering, i am a new user in Abaqus i getting well with it, but i always got axcessive distortion whenever i rty to run for high strain rate probelm. if some of you kindly can give me some hinte it will be great.

 thanks in advance 

Hi every body

i modeled a plane with a notch with elastic-perfect plastic material. somewhere in model the stress reaches above the yield stress

so i think the reason is that ANSYS reports the nodal result output by default wish they interpolated from integration points results.

i want to see the integration points results but i dont know where to finde them.

In shape memory alloy, Recovery strain is the strain at the start of the martensite to austenite transformation to finish of the same transformation.if we assume the material is initially in the austenite state. is it right about wat i thought about recovery strain???

I am doing my Masters degree,project is on
Shape memory alloy(NITINOL)......does any body know how to model SMA
using Patran and MSC.Marc?????

Is Your Thesis Hot? Or Not?
