Dataset on simulating the variability and scale effect for slow crack growth in Hi-Nicalon SiC-based tows: a parametric study
Description
The data are related to a research article entitled “Simulating the variability and scale effect for slow crack growth in Hi-Nicalon SiC-based tows: a parametric study” about the prediction of time to failure for Hi-Nicalon SiC-based multifilament tows under static fatigue conditions at intermediate temperature and ambient air. Focus was placed upon understanding parameters affecting the scale effect on stress exponent. In other words, why n = 12.6 on filament whereas it falls to 8.4 on multifilament tows, and how this can be transcribed through a Monte Carlo simulation? The concept behind these simulations can be summarized as follows: combine the filament strength and applied stress distributions, the latter being related to fiber slack, under a deterministic lifetime prediction model. 2 Monte Carlo algorithm including or not the global load sharing phenomenon are given in “Hi-Ni simulation load sharing.xlsx”. The “Stress-strength-lifetime data.xlsx” file link the lifetime of a tow and the parameters (applied stress and strength) for the critical fiber piloting its failure. Scatter for lifetime vs. applied stress (mean stress to tow σapp.t(γ = 14%), actual stress to tow σapp.t(γ) and stress to critical filament σapp.f(αt)) are presented, supporting the supplementary document.
