【Abstract】 Originating from Robert Hooke’s law and equilibrious equations, and using the theory of the complex variable function, this paper transfers the rectangle region in which the cracks emerge into the upper-half part of f plane by means of conformal mapping. Then according to the theory of reference [1], we have found the solution in closed form, thereby the stress intensity factors are derived更多还原
