Computer Analysis for Dynamic Response of Beams and Plates on Elastic Foundations.

Abstract

The current Air Force Nondestructive Pavement Testing (NDPT) method requires a rational method to evaluate pavement layer modulus values. A reasonable step toward the development of such a method is computer analyses of elastic layered systems subjected to dynamic loading. This research adopts the Method of Direct Analysis which uses the impulse-momentum laws and constitutive relations but bypasses the explicit use of differential equations. As a result of the research, two computer programs were developed, one for infinite beams and the other for infinite plates both on elastic foundations. To demonstrate the effectiveness of the developed computer programs, response analyses were made for sustained, pulse and sinusoidal loadings. The results for sustained loading on an infinite beam agreed very well with an available exact solution. It was concluded that the Method of Direct Analysis is an effective tool for dynamic response analysis of elastic layered systems. (Author)
