Abstract: Minimum-weight design of a portal frame for alternative combinations of horizontal and vertical loads is discussed. It is shown that the usual proof of the existence of a Foulkes mechanism as ...

Abstract: The paper is concerned with failure by plastic flow of the matrix of a fiber-reinforced composite sheet. For unidirectional reinforcement, a completely general state of plane stress in the ...

Abstract: The paper presents a uniform method of treating a variety of problems of optimal design of sandwich structures. The design procedure consists of two steps: The integration of an optimality ...

Abstract: The paper treats the visco-plastic flow of a circular plate that is simply supported along its edge and subjected to a uniformly distributed transverse load. The material of the plate is ...
