1. The problem statement, all variables and given/known data I have to solve for the stress-strain curve of a tensile test(materials science) given the following data: d0 = 10 [mm]; d=9.925[mm] (average after d1' and d1'') and L0 = 100[mm]; I have already solved the problem and charted the diagrams. But I would be most grateful if someone would be able to assist me in producing the numeric simulation. I am using Comsol 4.2 and the solid mechanics module. I've simplified the 3d model to a single cylinder of diameter 10[mm] and length of 100[mm]. I am applying a force of 11.39[kN] to both ends but the solver fails to complete and if I change some properties then it completes but the deformation does not show. 3. The attempt at a solution It seems that I am unable to link images at the moment. If someone is interested I would be ok with messaging them links to the gui screenshots and my results.
