Extension of high-fidelity time-domain spectral element . . .
本研究首次扩展了高保真时域谱元法（TD-SEM），建立了一种相场模型，用于准确有效地解决固体中的断裂问题。 TD-SEM结合了有限元法的灵活性和谱法的精度。与标准有限元方法相比，TD-SEM在谱元内采用高阶形状函数，在求解连续介质力学方程方面具有更高的精度和效率。相场公式捕捉复杂的裂纹行为，包括起始、扩展和分支，而不依赖于预定义的裂纹路径。将TD-SEM与相场法相结合，创造了一种混合技术，利用了两种框架的优势，能够精确预测固体中复杂的裂缝模式。本研究表明，相场TD-SEM与相场FEM和最近报道的加速相场模型相比，在几个方面表现出优越的性能：收敛速度明显更快，即使裂纹扩展区域网格更粗也能保持更高的精度，并且计算量更少。
