are the material properties which enter the constitutive equation for linear-elastic deformation; the elastic limit, σy, is the material property which enters the constitutive equation for plastic flow; the hardness, H, enters contact problems; the toughness JIC enters that for brittle fracture. In...
This correlation has been done as input for a new system being developed to quickly characterize sea ice properties. The results indicate a very good correlation (r2= 0.77) between the flexural strength (σf) and the brine volume (νb) with a functional form σf = 1.76 e−5.88√νb ...
Based on the world-wide researches,the reasonable and feasible testing conditions of direct tension for asphalt mixture included specimen dimension,judgment,controlled mode,load frequency and test temperature are determinated. With the fatigue test results by various strain level,equation of strain-life ...
the basic rule is to balance between shear and fracture. This can often be evaluate the cross section, shear zone is burnished and so shiny, fractured zone is dull because compressive forces exceed the ultimate strength of the sheet. Too tight clearances result in deeper shear zones and ...
Determination of valid R -curves for materials with large fracture toughness to yield strength ratios Crack growth resistance curves are derived from a generalised theory of quasi-static crack propagation due to Gurney and Hunt. Both the subcritical and con... AG Mai,AG Atkins,RM Caddell - 《...
