NURBS-based isogeometric analysis of buckling and free vibration problems for laminated composites plates with complicated cutouts using a new simple FSDT theory and level set method

We combine the isogeometric analysis, the level set and a simple first-order shear deformation theory (S-FSDT) to form a new effective and accurate approach for simulating free vibration and buckling problems of laminated composite plates with cutouts. The problem domain is discretized using non-uniform rational B-spline (NURBS) basis functions, which are utilized for geometry and field variables approximation. In S-FSDT, the shear locking...
