Several nonlinear Boundary Element (BE) analysis schemes in nonlinear solid mechanics are reviewed and discussed briefly in this paper. The original BE method is well-known to require inevitably domain discretization for the nonlinear problem. However successful schemes developed during these two decades made it possible to treat wide variety of the indicated problems without domain discretization; that is boundary only analysis, which is thought to be one of the most outstanding feature of the BE method among others. Geometrical nonlinear and material nonlinear cases are typical in the nonlinear solid mechanics. Dual Reciprocity Method (DRM) Multiple Reciprocity Method (MRM) are bases for a conversion of domain integral appearing in the integral formulation of the problem to the corresponding boundary integral either in solid mechanics or in other field problems. Other conversion schemes such as Computing Point Method (CPM), Analog Equation Method (AEM) and special techniques distinct from the above-mentioned types have been presented and applied.
