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缝的工程结构的安全评估，这几乎总是结构系统中最薄弱的部分。基于缩放边界多面体单元和数学编程，将建立新的数值方法来模拟界面和裂纹面的接触并模拟可变载荷下的裂纹扩展。预计所开发的数值模拟工具将是稳健且全自动的。该项目的预期成果是一种创新的数值模拟技术和一种合理的预测工具，可用于经济有效且及时的工程结构规划、设计和管理。
