Hey all, I want to calculate the stress and strain on a beam using MATLAB and I would also like to make a stress-strain curve as well. The problem is as follows: I have a hollow rectangular aluminum beam that is fixed at both ends. I have the material properties and the dimensions of the beam. The beam is 60 cm in z (length), 5 cm in x (width), and 3 cm in y (depth?). There is a load on this beam at let's say 40 cm from the wall (the other end is supported by another beam attached to ground). The load is approximately (40kg)(9.8m/s^2). Is there any way I can make a figure of this beam in MATLAB indicating where the load is applied and then calculate the stress and also plot stress-strain curve? Or if anyone has any references that would also help greatly. Thanks in advance!
