## Simpleware Case Study: Fuel Cell Microstructure from FIB Data

In this case study, based on work carried out at Imperial College and University College London, research was carried out into the performance of solid oxide fuel cells (SOFCs). The microstructure of an SOFC electrode was obtained using FIB tomography, and a volume mesh generated in Simpleware software, with the model then exported to Abaqus CAE. Boundary conditions were set in the solver and stress analysis conducted, which were able to approxiamte peak maximum principal stresses in response to thermal expansion.

## True Stress-Strain curve of metals

Hi everyone!

I was hopping to find some help over here. I just need some references or links to the true stress-strain curves of differents metals. I'm working with Tin and i'm going to do run some compression test to valid an analitic method. In order to do this, I need the strain-hardening exponent (n) and the strength coefficient (C) and it's being impossible to find those.

## Stress Analysis (Static & Dynamic test) of ISO Tank Container

Dear Colleagues,
I'm trying to model the ISO tests (as per ISO 1496-3) for a tank container subjected to static and dynamic loading using finite element technique. Regrading this work sufficient research papers are not available. Another thing is that, for fail-safe design and fatigue analysis there is no such documents known to me. Can you please help me in this regard?
Guidance from experienced colleague is highly solicited.

hi

Question 4:

A 2380 Nm torque is applied to gear D due to input torque from the motor at A, as shown in figure 4. Shafts 1 and 2 are both solid steel, 44 mm in diameter and 600 mm long. Gear B has a diameter of 250 mm and gear C has a diameter of 350 mm. The shear modulus G for steel is 80GN/m^2

Most active research in stereology is done in medical and biological community.

## Elastoplastic Indentation Stress Field

This model has a simple closed-form analytical expression, matching with finite element results nearly perfectly.
