摘要

摘要: 对现有的各种偶应力理论进行了认真的再研究,目的是要提出一个耦合型的Noether定理并由此重新建立偶应力弹性动力学的较为完整的守恒定律和相应的均衡方程。这里给出了新的各种守恒定律和均衡方程的具体形式,并建立起从给定的不变性要求所得到的这类守恒定律的确切属性。最后,由这里的结果自然地推导出各种特殊情形;并可自然地过渡到微极连续统的结果。

Abstract: The existing various couple stress theories have been carefully restudied.The purpose is to propose a coupled Noether.s theorem and to reestablish rather complete conservation laws and balance equations for couple stress elastodynamics.The new concrete forms of various conservation laws of couple stress elasticity are derived.The precise nature of these conservation laws which result from the given invariance requirements are established.Various special cases are reduced and the results of micropolar continua may be naturally transited from the results presented in this paper.
