Stress-strain analysis via CosmosWorks

Question asked by 1-8EV3K2 on Apr 6, 2010

Dear all,


Im a new user of Cosmosworks.. here i have a problem .. im doing simulation for Kelvin structure@ tetrakaidecahedral. this model usually used to model the foam structure...i have 3 sizes of model which is have different thickness.. when im doing the compression test using static analysis the Von Mises given is different... the problem is when i plot the stress strain curve the slope for all sizes is the same...actually i would like to know the modulus for my foam when im using different thickness...Here i attach the example of my study .. i really need your help why it happen... its caused by the load or anything.....your help is very appreciated
