The research will include advanced numerical modelling using existing software and development of new software. Small scale experiments will be performed within the University of Sheffield structures laboratories to validate numerical models.The experiments will involve subjecting small scale (100mm) cubes of concrete to temperatures of up to 300 degC, as well as standard testing under multiaxila compression.High-fidelity multiphysics finite element models will be implemented drawing on state-of-the art techniques in computational mechanics. These will be implemented using the commercial finite element code Comsol Multiphysics; and the open-source finite element code Code_Asterâ.

这项研究将包括使用现有软件和开发新软件的高级数值模拟。小规模实验将在谢菲尔德大学结构实验室进行，以验证数值模型。实验将包括将小尺寸（100毫米）的混凝土立方体置于高达300摄氏度的温度下，以及在多轴压缩下的标准测试。高保真的多物理场有限元模型将利用最先进的计算力学技术来实现。这些将使用商用有限元代码Comsol Multiphysics实现；以及开放源代码的有限元代码code_aster<e:1>。
