项目摘要
In this study, a strain gradient theory of crystal plasticity that accounts for the self-energy of geometrically necessary dislocations was developed. Then, an implicit iterative finite element scheme for the theory was also developed. It was demonstrated that this scheme is superior to the conventional method from the point of the incremental stability as well as of the computational efficiency. Furthermore, to verify the theory, the formulation of a homogenization theory for discrete dislocation dynamics analysis was successfully performed.
在这项研究中,发展了晶体塑性的应变梯度理论,该理论解释了几何必要位错的自能。然后,还开发了该理论的隐式迭代有限元格式。事实证明,该方案从增量稳定性和计算效率方面优于传统方法。此外,为了验证该理论,成功地建立了离散位错动力学分析的均质化理论。
