Claim One:
1. A method of obtaining numerically simulated structural behaviors of brittle material comprising: receiving, in a computer system having a meshfree-method application module installed thereon, a meshfree model containing a plurality of particles to represent a structure made of brittle material subjected to cracks; and conducting, with the meshfree-method application module, a numerical time-marching simulation based on damage mechanics for a plurality of solution cycles using the meshfree model, at each non-initial solution cycle, performing following operations: a) determining one or more damage zones in the structure from simulated structural behaviors obtained in immediate prior solution cycle; b) dividing the particles of the meshfree model into a first group representing said one or more damage zones and a second group representing remaining particles of the meshfree model; c) applying a meshfree regularization scheme by modifying each particle's strain field of the first group with a morphing function that ensures a homogeneous jump condition along respective borders of said one or more damage zones; and e) obtaining structural behaviors of the structure using a meshfree stabilization scheme that applies to all of the particles' strain field.
