A lattice model has been developed to explore impact damage patterns in brittle materials . The damage evolution was modelled as a process involving the change of strain-energy distribution ...
In this contribution, we propose a dynamic gradient damage model as a phase‐field approach for studying brutal fracture phenomena in quasi‐ brittle materials under impact ‐type loading conditions ...
an effective numerical procedure for simulating impact failure responses, a three‐dimensional computational damage model is developed in this paper. The propagation of the failure wave behind the elastic shock ...
Percussion drilling, wave propagation in damageable media, and the evolution of damage caused by repeated impacts during percussion drilling in brittle disordered materials are investigated. Analytic ...
In this work, we have developed a novel bond-associated non-ordinary state-based peridynamic (BA-NOSB PD) model for the numerical modeling and prediction of the impact response and fracture damage ...
The brittle nature of electromagnetic (EM) window and dome materials limits electrical and magnetic performance due to impact of sand particles, hailstones and raindrops. The damage and fracture ...
elastic- damage model alone is insufficient to meet the requirements for simulating the deformation of materials with ductility, and the computational cost of the discrete-element makes it a bottleneck ...
This study explores the application of numerical analysis and material models to predict ice impact loads on ships and offshore structures operating in polar regions. An explicit finite element ...
‐induced (inherent) flaws and deformation‐induced flaws on fracture initiation in a brittle material are discussed. Recent developments in analytical modeling of indentation‐ and impact ‐induced damage ...
. The created software can be used in the analysis of the results of intense energy impacts in engineering practice, verification of models of volumetric fractures, and spallation in brittle materials , as well ...
