Abstract: This paper introduces a few new equations and a performance nomogram for the design of helical compression springs. The procedures for calculation are simple, speedy, and accurate.

Abstract: Moisture in composite materials has been the subject of considerable interest in the past decade. Many studies have shown that moisture directly causes damage in graphite/epoxy composite materials. ...

Abstract: In this paper, an inverse problem is solved for estimating parameters of a steamdriven water–lithium bromide (LiBr) vapor absorption refrigeration system (VARS) using a differential evolution (DE)based inverse approach. ...

Abstract: The effects of periodic transverse velocity fluctuations are investigated for boundary-layer flow over a flat plate. The method used is a perturbation expansion of the three-dimensional boundary-layer ...

Abstract: An analysis is made of the response of a system with bilinear hysteresis to random excitation. It is shown that for moderately large inputs, the additional damping created by the bilinear ...
