In the finite-element method, a finite-element mesh is necessary. For elastoplastic and nonlinear problems, the conventional boundary-element method (BEM) also requires a mesh for domain integrals. The main advantage of the conventional BEM formulation is decreased for those problems. The meshless triple-reciprocity BEM makes use of internal points instead of a domain mesh. In this research, the meshless triple-reciprocity BEM is applied to various elastoplastic, non-homogenous, and unsteady problems with domain integrals. These results have been presented in 12 papers and 7 international conference proceedings. Using the research results for unsteady problems, one chapter of a free e-book is available for computational engineering researcher.

在有限的元素方法中，必须使用有限元网格。对于弹性和非线性问题，常规边界元素方法（BEM）还需要用于域积分的网格。对于这些问题，常规BEM公式的主要优点降低了。无网状三重生BEM使用内部点而不是域网。在这项研究中，将无网状三重生BEM应用于域积分的各种弹性塑料，非遗传性和不稳定的问题。这些结果已在12篇论文和7篇国际会议记录中提出。利用研究结果解决不稳定问题，可以为计算工程研究人员提供免费电子书的一章。
