Abstract:
The lattice analogy is a scheme for solving two-dimensional stress problems in which the involved mathematical methods of the theory of elasticity are replaced by simple computations. The solid section is replaced by an equivalent lattice or framework which may be solved by methods applicable to indeterminate structures. Stress distribution in sections of complex shape and with complex loading may be determined by successive approximations which involve only substitution in simple equations. The method is illustrated by application to the problem of stresses in deep beam with off-center loading.
