Sentence examples for models of crack from inspiring English sources
The study focuses on coupling of reliability analysis algorithms with deterministic, numerical models of crack propagation.
Historically, models of crack deflection have been developed using either a strength-based or an energy-based fracture criterion.
In this work, crack coalescence and fatigue crack closure are incorporated into established models of crack propagation analysis.
The problem is formulated by combining the first passage failure model with stochastic models of crack propagation.
It is possible to optimize these means using developed special engineering models of crack propagation in structure components subjected to aggressive hydrogen environment and cycling.
Importantly, we point out that all available models of crack propagation in brittle solids yield the same results in terms of scaling, and thus, while the single length scale we uncover is an effective measure of the state of fragmented ice, its physical interpretation is elusive and needs to be probed by direct experiments.
Based on the proposed model, 5,120 numerical models of cracked tubular K-joints subjected under balanced axial load are analyzed in the study.
Also, the ratio of GF/Gf, which is applied for calibration of numerical models of cracking at different ages, is equal to 2.70.
Localized flexibility models of cracks enable one for simple and effective representation of the behavior of damaged beams and frames.
Computational models of cracked composite cylindrical shells are developed by exploiting a special meshing scheme in which the element size is reduced incrementally from the element size employed in the uncracked region by approaching the crack tip.
Based on ANSYS software, mixed elements combining beam elements and solid elements are adopted to establish the finite element (FE) models of cracked cantilever beams where the crack levels are evaluated by introducing the area damage factor, i.e., the ratio of the damage area to the cross-sectional area.
