CRACK DELOPMENT AND DYNAMIC NATURE OF CRACK PROPAGATION IN STRUCTURES
This paper aims at finding the sources of crack development in modern structures at an elevated temperature and under severe vibrations due to excessive load magnitudes and also of ceismic vibrations. In the present paper attempts have been made for solving the problems relating to large amplitude vibrations of uniform elasto plastic plates and shells under both static and dynamic loads using the method of constant deflection contour lines8-15. Also, the effect of crack development and its propagation through the structures have been studied rigorously. The works in this field by numerous researchers are discussed shortly in the introduction and considering all the assumptions made by them after proper correction compatible with the boundary conditions, the present author tries to develop the equations with consideration of multi aspect crack generating factors and their impact on the time periods of nonlinear vibration of the structures and the results obtained for a crack structure are presented along with that of the non cracked structure.
