An innovative approach based on machine learning predictions stemming from a representative dictionary of finite element analysis (FEA) generated prototypes was developed. The proposed approach predicts multiple severity-based...

... the strains associated with a dent. It has been well established that three-dimensional (3D) elastic-plastic Finite Element Analysis (FEA) is the most accurate in the denting process simulation and dent strain calculation. However, FEA modelling of dents interacting with other threats can be extremely...
