Evaluation of fracture parameters in cracked plates using an extended meshfree method

In this paper, an extended meshfree method approach is developed for numerical analysis of cracked plates using the First order Shear Deformation Theory — FSDT. Extrinsic enriched functions are employed to capture the jump in deflection and rotation fields, as well as the stress singularity in the vicinity of crack tip. Meshfree approximation of field variables is done by the Radial Point Interpolation Method, which possesses the desirable...
