چکیده انگلیسی
The two-dimensional inclusion problem of elasticity has been extended to treat general non-elliptic shapes described as (x12)p/2+(x22/α2)p/2â¤1, p â¥Â 2. By using the Green function, the average Eshelby tensors are evaluated and elastic strain energy of the superelliptic inclusion is calculated for a material with cubic elastic anisotropy. In addition, by introducing the isotropic interface energy, equilibrium inclusion shapes to minimize the sum of elastic strain energy and interface energy are discussed as a function of the size and shape of the two-dimensional inclusion. It is found that an intermediate shape between a circle and a square or between an ellipse and a rectangle can be a minimum-energy shape under certain sets of given conditions.
