Stress resultant intensity factors evaluation of cracked folded structures by 6DOFs flat shell meshfree modeling

Mixed-mode stress intensity factors evaluation of flat shells under in-plane loading employing ordinary state-based peridynamics

“…[22], membrane SIFs are generally greater than bending SIFs in thin cracked plates. In thin-walled structures, most of the loads are transferred to the structure as in-plane stresses [22,23]. Thus, in-plane loads are considered throughout the present paper.…”

A non-polynomial axiomatic framework for modelling and bending analysis of doubly curved spherical and cylindrical shells: An analytical solution

“…Other numerical methods like mesh-free methods are also used to analyse curved composite structures. 49–53 Shah and Batra 54 used third-order shear and normal deformation theory and FEM to predict the deformation of doubly curved shells. Pasquali and Gaudenzi 55 presented a geometrically exact non-linear formulation for modelling the equation of motions for cylindrical and spherical laminated shell structure.…”

A smoothed variable horizon peridynamics and its application to the fracture parameters evaluation

“…Finally, the authors proposed improvements on the state-based PD addressing the issues associated with application of boundary conditions and nonuniform grids based on the findings from the study [20]. In the meshfree methods, the non-uniform particle arrangement for the demanded area was employed and mixed-mode SIFs of shear deformable plates [21][22][23] as well as buckling of cracked cylindrical and flat shells [24] were studied. In addition, same concept was recently applied to geometrical non-linear analysis of shells by a meshfree particle method [25].…”
