Effect of strain rate on transient local strain variations in articular cartilage
Journal of the Mechanical Behavior of Biomedical Materials, 2019The non-homogeneous, anisotropic material properties, and triphasic nature of articular cartilage enables diarthrodial joints to withstand large and complex physiological loading conditions. To develop biomaterials that provide similar functional properties as those found in articular cartilage, it is vital to have knowledge of the strain distributions

Compressive Strain Rate Effects of Concrete
MRS Proceedings, 1985ABSTRACTSince good constitutive laws are required to model correctly the behaviour of concrete under impact loading, it is necessary to determine the complete stress-strain response of concrete at varying strain rates. Conflicting evidence emerges about whether the critical compressive strain (defined as the strain observed at maximum stress) increases

Effect of Thermobaric Explosive on Strain Rate
Advanced Materials Research, 2014In order to analyze the effect of RDX-based thermobaric explosive on strain rate, the stress-strain curves with different strain rates were measured by using the Split Hopkinson Pressure Bar (SHPB) and resistive strain testing technology. The different strain rates were obtained by changing the length to diameter ratio (L/D=0.46~0.92) and speed of the ...

Strain-Rate Effects in Metals at Large Shear Strains
1983Many problems in ballistics involve very large shearing deformation occurring at high deformation rates. Such problems include, for instance, explosive formation of shaped charge jets or selfforming fragments and the defeat of thick targets by long rod penetration.

Strain Rate History Effects and Dislocation Substructure at High Strain Rates
1983A brief review is presented of strain rate history and temperature history effects during the high strain rate deformation of metals with special emphasis on the BCC metals. Possible explanations to account for history effects are reviewed. Experiments are described in which single crystals of aluminum are deformed at various strain rates. Observations

Strain Rate Effects in Porous Materials
MRS Proceedings, 1998ABSTRACTThe behavior of metal foams under rapid loading conditions is assessed. Dynamic loading experiments were conducted in our laboratory using a split Hopkinson pressure bar apparatus and a drop weight tester; strain rates ranged from 45 s−1 to 1200 s−1.

The effect of strain rate on rock strength
Rock Mechanics and Rock Engineering, 1991The effect of the strain rate on strength has been evaluated for two widely different rock types, a brittle limestone (Tyndallstone) and a ductile salt rock (Lanigan potash rock). Results of static and dynamic fatigue tests on Tyndallstone, a dolomitic limestone, show an increase in strength with increasing strain or stressing rate although the rate ...
