ELASTIC TRANSVERSE IMPACT ON BEAMS

Abstract

Present investigation were carried out to study photoelastically the stress distribution in a simply supported beam with over-hangs subjected to a low velocity central- and quater- span-impact loading by light strikers keeping beam/ striker weight ratio constant (2.675), and then comparing the results so obtained with those in similar simply supported beams made of other materials sujected to central- impact loading s form an analysis of dynamic strain gauge data. Interesting new findings were obtained from the results of the present investigation and also from results reported in the literature in this respect. In modern times dynamics stress analysis is becoming increasingly important for various engineering applications. Although significant amount of insight in these respects have been developed, the subject being rather intricate would continue to attract of more research workers in future. A beam is a common structural element, and in several applications, simply supported beam...
