SPC simulation data

The sensitivity of the SPC method to nonlinear wave-material interaction was numerically investigated. Parametric studies were conducted by varying the levels of (i) excitation, (ii) material nonlinearity, (iii) defect nonlinearity, and (iv) defect scattering. The obtained results indicated that the SPC method lacks sensitivity to acoustic nonlinearity.This dataset contains the COMSOL Multiphysics simulation models, a Matlab postprocessing code, and numerical results in an Excel workbook.本研究对SPC方法针对非线性波-材料相互作用的敏感性开展了数值仿真分析。通过改变以下四类参数的取值完成参数化研究：(i) 激励强度、(ii) 材料非线性程度、(iii) 缺陷非线性程度、(iv) 缺陷散射特性。研究结果表明，SPC方法对声学非线性缺乏敏感性。本数据集包含COMSOL多物理场（COMSOL Multiphysics）仿真模型、一套Matlab后处理代码，以及存储于Excel工作簿中的数值仿真结果。
