This project aims to address the safety assessment of engineering structures considering interfaces and cracks, which are nearly always the weakest parts of a structure system. Novel numerical approaches to model the contact of interfaces and crack faces and to simulate crack propagation under variable loads will be established based on the scaled boundary polytope elements and mathematical programming. It is anticipated that the developed numerical simulation tool will be robust and fully automatic. The intended outcome of this project is an innovative technology for numerical simulation and a rational predictive tool useful for cost-effective and timely planning, design and management of engineering structures.

该项目旨在解决考虑界面和裂纹的工程结构的安全评估，这些工程结构几乎总是结构系统中最弱的部分。将基于缩放边界多层元素和数学编程建立界面和裂纹面接触并模拟裂纹传播的新型数值方法。预计开发的数值仿真工具将是强大且全自动的。该项目的预期结果是用于数值模拟的创新技术，也是一种合理的预测工具，可用于工程结构的成本效益和及时计划，设计和管理。
