The Behaviour of an Infinite Elliptic Bar Subjected to Impulsive Loads

概要

論文の詳細を見る
In the cases that an impulsive load (impulsive longitudinal load, impulsive shearing load or impulsive bending load) is applied, the stresses and the strains induced in an infinite elliptic bar are obtained. The analysis is based on the fundamental equations of three -dimensional elasticity. Laplace transform and Fourier transform techniques are utilized for the analysis. The inverse transforms are carried out under the following two assumptions ; (1) The eccentricity of the elliptic cross section is small. (2) After the application of the impulsive load, the elapsed time is not very short. The results obtained from the analysis are compared with the results of a circular bar.
