    Bulk Vs Foam Stress-Strain ?

    Hello everybody I'm Working on Representative Volume Elementary (RVE) of Aluminum Foam. I generated the Geometry of a foam with %50 porosity. The main goal is to mimic the experimental Stress-Strain Curve and get the same response of foam that was achieved in reality. Therefore, different...

    Simple Structure Optimization get Twisted ...

    Hello everybody. I'm working on simple structure from a paper, "On the topological optimization of horizontal links in eccentrically braced frames", That need to be validated. So far, I think done all steps according to the source paper but still there is something fishy that I can't figured...

    No answer ?

    Hi everybody I am new with MATLAB, also one of my friends ask me to integrate from this: And I write this: syms x a b c f=(sqrt((x-a)^3))/(exp((x-b)/(sqrt(2)*c))^2); A=int(f,x,a,inf); But after run the Codes, Value A is: int(exp((2^(1/2)*(b - x))/c)*(-(a - x)^3)^(1/2), x == a..Inf) If pretty...
