摘要: The two-dimensional (2D) Eshelby tensors are discussed. Based upon the complex variable method, an integrity basis of ten isotropic invariants of the 2D Eshelby tensors is obtained. Since an integrity basis is always a polynomial functional basis, these ten isotropic invariants are further proven to form an irreducible polynomial functional basis of the 2D Eshelby tensors.

关键词: relative motion, inertial force, generalized force, invariance, representation theorem, Eshelby tensor, isotropic invariant, irreducible functional basis
