Heyman in his fundamental and pioneering studies of masonry arches and vaults. Here the masonry body will be represented by an assemblage of rigid particles of stones, held together only by compressive forces, and liable to crack as soon as tensile stresses begin to develop. The very small size of the stones, compared to the overall dimensions of the body, permits a treatment in terms of a continuum. The admissible mechanism displacement and stress fields of the masonry body are analysed, and an appropriate formulation of the virtual work equation is given. A variational inequality, involving the sign of the work of external loads along the mechanisms-necessary and sufficient for the existence of the admissible equilibrium states-is then proved. The collapse of the body is then properly formulated and, finally, new versions of the kinematical and statical theorems of failure are proved.
