Most related studies are based on the linearized assumption that carrier concentrations are limited to present very small variations such that the nonlinear drift current term can be ignored at all. In this study, the nonlinear effect between an elastic wave and carriers in a PS rod is discussed in detail. The multi-field coupled nonlinear differential equations are numerically solved by finite element method. It is found that the electric transient disturbances are deviated from the standard harmonic distribution by comparing with the linear solutions. The carriers driven by the alternating electric field are more likely to accumulate at the crest when their drift movement motion is consistent with the propagation direction of the traveling wave. Oppositely, the troughs of the carriers tend to depletion due to the nonnegative property of the carriers. In addition, the nonlinear characteristics of the carriers and the dispersion properties of the coupled wave become stronger with the decreasing doping concentrations. These studies will provide guidance for theoretical analysis of wave propagating in PSs and design of acoustoelectric devices.","PeriodicalId":49186,"journal":{"name":"International Journal of Applied Mechanics","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44363774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variational forms of residuals for the governing equations of solid mechanics are utilized, and the residual is evaluated over the entire computational domain by employing domain decomposition and polynomials test functions. A parameter network is introduced and initial and boundary conditions, as well as data mismatch, are incorporated into a total loss function using a weighted summation. The accuracy of the model in solving forward problems of solid mechanics is demonstrated to be higher than that of the finite element method (FEM). Furthermore, homogeneous and heterogeneous material distributions can be effectively captured by the model using limited observations, such as strain components. This contribution is significant for potential applications in non-destructive evaluation, where obtaining detailed information about the material properties is difficult.","PeriodicalId":49186,"journal":{"name":"International Journal of Applied Mechanics","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47398189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
