IntroductionBrittle failure is the product of the creation, growth and accumulation of … WebMar 31, 2024 · Both curves show significant strain softening, which means the fibers soften (slope decreases) as the strain increases. The 75:25 fibrinogen:PCL fibers exhibited a linear slope until 12% strain (the yield point); then, the slope decreased significantly, and the fiber broke at 69% strain. ... The modulus increases by a factor of about 5 for the ...
Factor of safety of strain-softening slopes
Did you know?
WebIt has little influence on the stress field, but the factor of safety depends on the stress field. For the slope with strain-softening behavior, changes of elastic modulus will affect the strain field, and thereby influence the values of the strength parameters, the mechanical behaviour and the stability of slope will therefore be changed. WebMay 2, 2011 · Numerical modeling showed that the formation of gas hydrates in the shallow sedimentary layers could considerably affect the factor of safety of the studied slope. The present work showed clearly that the strain-softening behavior of gas hydrate-bearing sediments has relevance for the stability of submarine slopes.
