Abstract : A modified Particle-In-Cell (P.I.C.) method has been developed for solving two-dimensional nonlinear elasticity problems. The method is demonstrated by determining the stress concentration in an elastomeric sheet with a rigid circular inclusion subjected to large equi-biaxial deformations. The results indicate that the P.I.C. method might well be a desirable alternative to other numerical schemes for solving this class of problems. (Author)
