Strength prediction of a single lap joint under impact using meshless methods

Composites Part C: Open Access, 2023
The use of adhesive joints in structures subjected to dynamic loads, such as wind turbines and cars, makes it important to study them under those conditions. Numerical models are an integral part of that. Commonly the Finite Element Method (FEM) is used,

On the Factors Affecting the Accuracy and Robustness of Smoothed-Radial Point Interpolation Method [PDF]

, 2017
In order to overcome the possible singularity associated with the Point Interpolation Method (PIM), the Radial Point Interpolation Method (RPIM) was proposed by G. R. Liu. Radial basis functions (RBF) was used in RPIM as basis functions for interpolation.
