Poisson Ratio -- Finding a corresponding analytical solution for the strain

[QUOTE="Br--1995, post: 6414092, member: 683635"] [B]TL;DR Summary:[/B] Find a corresponding analytical solution for the strain in the x-direction caused by the poisson ratio. Hi, I ran into problems using the poisson ratio. For a FE simulation I created a simple 2D 1mm x 1mm block, and prescribed a 0.1 mm displacement at the top edge. Furthermore, the bottom edge is constraint in the y-dir, and the left edge in the x-dir. The material parameters are E = 100, and v (poisson ratio) = 0.3. Note the simulation is executed for a [U][I]plane strain[/I][/U] assumption! To verify the results I would like to solve the analytical solution for this problem. This is quite simple tbh, I use the 2D strain-stress relations for the plane strain problem. However, the simulation shows that the strain_yy = -0.1 (as expected) but the strain_xx = 0.04285714. I really cannot figure out the analytical solution for the strain_xx, I would expect this to be 0.03 (strain_xx = -v * strain_yy). I know that the 0.0428.. value should be the correct one, because I tried the simulation in different simulation software. Hopefully someone can explain me how to get this value analytically? Thanks in advance! [ATTACH alt="Situation_sketch.PNG"]272232[/ATTACH] [ATTACH alt="Displacement_x.PNG"]272231[/ATTACH] [ATTACH alt="Strain_xx.PNG"]272233[/ATTACH] [/QUOTE]
