A weak-form meshfree coupled with infinite element method for predicting acoustic radiation

To improve the computational accuracy and eliminate the element matching in the traditional method based on the finite and infinite elements, the coupling of the meshfree weak-form method with the variable order infinite acoustic wave envelope element (WEE) is studied in this paper and achieved by forming continuous acoustic shape function on an artificial interface, by which the infinite domain is divided into two subdomains where the meshfree...
