DOI: 10.1016/j.compstruct.2021.114147
Abstract: Abstract The conventional theories like CLPT, FSDT and HSDT used for the structural analyses of single or laminate composite structures are characterized by the type and order of thickness-wise displacement functions. Based upon this fact,… read more here.

DOI: 10.1016/j.finel.2020.103439
Abstract: Abstract Almost all the mesh-free methods are restricted to 2-D problems owing to the difficulty in generating 3-D grids. One effective way to overcome this limitation is to utilize the concept of hierarchical modeling for… read more here.
