概要

In this paper the fundamental investigations are performed to extend the probability of application of Caustics experimental method to various stress analytical problems in new studying fields. Under simplified two dimensional condition, the object of study is a half plane with discontinuously distributing oblique load divided 2 or 3 parts over loading region. Specimens are made of acrylate resin plate of about 3 mm thickness. The Caustics patterns formed by reflected lights from the both surfaces of plate are observed and those characteristics with loading conditions are investigated in detail. On the other hand the computational patterns based on optical theory are plotted. These two patterns are coincided accurately enough.
