Hydrogen-assisted cracking (HAC) usually causes premature mechanical failure of the material and results in structural damage hydrogen environments. A phase-field regularized cohesion model (PF-CZM) was proposed to address hydrogen-assisted cracking. It incorporated hydrogen-enhanced decohesion mechanism decrease critical energy release rate initiation progression a chemo-mechanical coupled environment. This is based on diffusion responses, driven by chemical potential gradients,...
Ceramizable phenolic resin matrix composites have a significant potential for widespread applications in the field of aerospace ablation. However, due to sharp decrease mechanical properties at elevated temperatures, composite fails meet requirements thermal protection as well load-bearing aircraft wide temperature range.

A new solution for the longitudinal displacement profile (LDP) is proposed based on three-dimensional finite-difference method. The improved convergence-confinement method (CCM) divided into two stages. In first stage, fictitious support pressure can be derived, representing acting periphery of tunnel by rock mass itself. second transforms to liner, and this progress reflects interaction between liner. According two-stage analysis, a computing procedure calculating deformation By comparing...
Crack propagation in ceramics is a highly quick, complex, and nonlinear process that occurs under thermal shock. It challenging to directly observe the evolution of cracks experiments due high speed unpredictability crack propagation.

This study employs the phase-field regularized cohesion model (PF-CZM) to simulate crack propagation and damage behavior in porous granite. We investigate how pore radius (r), initial crack-pore distance (D), pore-crack angle (θ) impact propagation. The simulation findings reveal that, with a fixed deflection distance, larger pores are more likely induce extension under identical loading conditions. Moreover, r θ keeping constant, can be divided into two stages: from its initiation lower...
