Im am trying to solve an exercise with Levy's theory for plates which is a Single Sine Series. As it is described in the books, i have to use a load pm(y) , with m=1,2,3,...M, but as a function of y. I will try to illustrate it in the following figure and also i will upload the file that I'm trying to create. It is in Mathcad 15.
I hope i'm clear enough because it is a bit difficult since i don't have it clear enough myself, unfortunately.
