Extension of the Linear Matching Method to frame structures made from a material that exhibits softening

Abstract:

This paper considers the problem of evaluating the maximum load that an elastic-plastic frame structure can withstand when material or element softening is present. Here we propose an extension of the Linear Matching Method to take into account material softening. The technique has two major steps: reduction of the total potential energy to obtain the solution of a linear problem and scaling of the resulting mechanism of deformation to maximize the load. Two procedures are evaluated for the s...
