Numerical Fatigue Analysis for Crack Propagation on Ti6Al4V Panel Using XFEM Method

Macromolecular Symposia, EarlyView.
ABSTRACT The aim of this work is the validation of a numerical model based on the XFEM method for the prediction of crack propagation in mechanical components subjected to cyclic loads. Through careful bibliographic research, it was decided to take as a case study the analysis of the propagation of a crack passing through a panel in an additive ...

A Coupled Extended Finite Element–Cohesive Zone Model for Hydraulic Fracture Propagation Under Poroelastic Effects Across Different Propagation Regimes

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

Behavior of a Novel Cyclic Olefin‐Based Hot‐Melt Adhesive in CFRP Adhesive Joints Compared to Conventional Epoxy‐Based Structural Adhesives

Polymer Composites, EarlyView.
Rate‐dependent performance of composite adhesive joints using thermoset and thermoplastic adhesives, in terms of toughness and fatigue behaviour. ABSTRACT A recently developed hot‐melt adhesive (HMA) based on cyclic olefin chemistry, supplied as a transparent, non‐tacky thermoplastic film with a distinctive polymer microstructure, was evaluated in this
