    Just a general question about Homogenization , when we are selecting the RVE , how much should it be smaller than the Macro dimensions of the model , to be counted micro , I mean only that one part of the model is being repeated is enough to define the periodicity or it should be very smaller in...

    We are so familiiar with composites that we almost forget what it is. Some say a composite material is a material which is anisotropic and heterogeneous. First, I would like to argue that anisotropy cannot be used to define composites although composites are usually anisotropic. We do have...

    Structures and materials often appear together and sometimes even used interchangeably. The main reason is that the boundary between structures and materials is not clear. Even our first solid mechanics course usually called either strength of materials or mechanics of materials  is...
