Abstract
Buckling strength analyses for cracked plates and cylindrical shells are carried out by efficient Reproducing Kernel Particle Method (RKPM). The accuracy and efficiency of the RKPM is examined by series of Finite Element Analyses (FEAs) as well as available reference solutions. Derivation of stiffness matrices is performed by Stabilized Conforming Nodal Integration (SCNI) and Sub-domain Stabilized Nodal Integration (SSCI) methods. Singular Kernel (SK) approach is employed so as to impose essential boundary conditions (BCs). Effect of crack size and crack orientation is investigated through numerical examples.
