TL;DR: In this article, the authors study the capabilities of Extended Finite Element Method (XFEM) to achieve accurate computations in non smooth situations such as crack problems, and show that the XFEM method ensures a weaker error than classical finite element methods, but the rate of convergence is not improved when the mesh parameter h is going to zero because of the presence of a singularity.

TL;DR: In this article, a Lagrangian smoothed particle hydrodynamics (SPH)-based model is used for high speed cutting numerical modeling, which can account for continuous to shear localized chip formation and also correctly estimate the cutting forces.

TL;DR: In this paper, a response surface is built from an initial Latin Hypercube Sampling (LHS) where the most significant terms are chosen from statistical criteria and cross-validation method.

TL;DR: This systematic survey aims at presenting the current trends in diagnostics and prognostics giving special attention to multi-model approaches and summarizing the current challenges and research opportunities.

TL;DR: In this article, the authors present a short description of the three dimensionnal elastic-model and the Kirchhof f-love plate model for thin structures and present a mixed variational formulation for bending plates.
