Bistable mechanisms have two stable equilibrium positions separated by a higher energy unstable equilibrium position. They are well suited for microswitches, microrelays, and many other macro- and micro-applications. This paper discusses a bistable buckled beam actuated by a moment input. A theoretical model is developed for predicting the necessary input moment. A novel experimental test setup was created for experimental verification of the model. The results show that the theoretical model is able to predict the maximum necessary input moment within 2.53%. This theoretical model provides a guideline to design bistable compliant mechanisms and actuators. It is also a computational tool to size the dimensions of buckled beams for actuating a specific mechanism.

The paper examines the effect of increased bottom plate projection for tanks with rigid ring wall foundations. A theoretical model, based on the existing model from Denham is proposed to determine the maximum projection length. The behavior of the tank, specifically near the bottom is studied till failure using FEA. The formation of plastic hinges in the bottom plate on the inside and outside of this joint is discussed in detail. The validity of the assumptions made by Karcher with regard to plastic hinges for obtaining the expression for the design life cycle in elevated temperature tanks is briefly analyzed.

Transparent polymer interlayer foils are widely used to increase the safety of glass applications, mainly in construction and automotive industry. In case one or more glass sheets in a laminate fracture, the remaining structural capacity (i.e. stiffness and strength) highly depends on the solicitation and mechanical properties of the interlayer. In such a post-breakage state, the interlayer is subjected to a complex combination of phenomena such as partial delamination, large strain deformation, strain hardening, rupture, etc. In part 1, an analytical model was presented to describe the mechanical behavior of glass laminates in a post-breakage state in which both glass plates are broken. In addition, a comparison of the theoretical model with experimental results is presented in part 2 below.
