新型FF-PINN模型为土工材料提供更快、更准确的分析

研究人员开发了一种傅里叶特征物理信息神经网络(FF-PINN),以解决岩土工程中弹塑性问题分析的局限性。传统的有限元方法(FEM)计算成本高昂,而标准的物理信息神经网络(PINN)则存在频谱偏差问题,无法准确捕捉弹塑性边界处的尖锐梯度。所提出的FF-PINN嵌入了随机傅里叶特征映射来减轻频谱偏差,与传统的PINN相比,实现了更高的准确性,并将训练时间缩短了一半。这一新框架为复杂的岩土工程分析提供了一种更有效、更准确的替代方案。 AI

影响 这项研究为复杂的岩土工程分析提供了一种计算效率更高、准确性更好的AI驱动的替代方案,有可能减少对传统、较慢方法的依赖。
