LOCAL AND BENDING STRESSES IN LAYERED MATERIALS WITH BONDED INTERFACE.
Abstract
The objective of this thesis was to obtain quantitative stress data for layered materials with bonded interface subjected to a static point load. Two distinct cases were considered: (1) local stresses due to a concentrated load applied to a semi-infinite composite body, and (2) bending stresses due to a point load applied to a composite beam whose vertical boundaries were fixed. A theoretical solution employing methods of numerical analysis where the composite is considered as a discrete continuum, and a experimental solution utilizing the technique of both photoelasticity and the morie method, resulted in compatible stress levels. Only stresses in the lower or core layer were considered. Variations in the stress level due to changes in material for the upper layer and thickness of the protective layer were examined. (Author)
