抄録

In this paper, it is described that the stress distributions will be calculated by using the complex stress function and conformal representation for an infinite plate, under any uniform edge force, containing an elliptical region filled with material having the modulus of elasticity (EI) and Poisson's ratio (υI) which are different from those (EM, υM) of the, plate.<BR>The results show the distributed stresses have almost same values as the edge ones (Oy ∞, τxy ∞), excepted the limited region of the tip of elliptical inclusion.<BR>And taking into consideration of stress concentration around an elliptical inclusion, the condition of rock fracture in principal stress co-ordinates is shown by straight line in the compressive stress region.<BR>Also the experimental results used a sandstone are fitted with the theoretical calculation (υI/υM=0.6, EI/EM=0.1).
