   Hello, I want to model a curved beam using VABS. I did the cross-sectional analysis of the curved beam with an initial curvature k2. Then, I got the cross-sectional stiffness matrix of the curved beam. The question is that can I rearrange the obtained cross-sectional stiffness matrix of...

   Inspired by the discussion on another website, I am thinking about a new journal with the following attributes: 1. Has its own arXiv service so that submitted papers become instantly public. I can see three benefits of doing this: 1) instant copyright protection. The authors do not have to worry...

   With the increasing demand and needs for composite materials in many fields of industry, analysis and simulation of composite materials are becoming more and more important and challenging. In theory, one can use the finite element analysis (FEA) to conduct a direct numerical simulation (DNS) for...

   Terms like Euler-Bernoulli beam or Timoshenko beam are often used in the literature or technical communications. I personally think these terms are confusing because they use a model along with its associated assumptions to name a structure. Actually a beam structure is a solid with its axis...

    Verification and validation (V&V) are important considerations for a computer simulation code. It is commonly understood that verification is to check whether a computer code solves the equations correctly while validation is to check whether a computer code solves the correct equations....

    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...
