Resistance of full-flow penetrometers in rate-dependent

Accurate determination of in situ shear strength using full-flow penetrometers (cylindrical T-bar and spherical ball) requires thorough investigation into soil characteristics such as strain rate dependency and strain softening, which have been shown to have a significant influence on the resistance factors relating penetration resistance to the soil shear strength measured in laboratory tests.

Lithium Mechanics: Roles of Strain Rate and Temperature

11/29/2019 · However, the stress-strain curve at the lowest temperature (198 K) appears to show some effects of strain hardening. This low-temperature, high-stress behavior is consistent with standard models of creep and plasticity, where glide dominates if the stresses reach high-enough levels.

The Effects of Load History and Design Variables on

A series of strain histories from the experimental tests and fiber-based analyses were applied to the finite element model to study their impacts on the strain limit for reinforcing bar buckling. Initial analytical investigations have shown significant impact of load history on the strain demand to lead to reinforcing bar buckling in the ...

Johnson–Holmquist damage model - Wikipedia

The Johnson-Holmquist material model (JH-2), with damage, is useful when modeling brittle materials, such as ceramics, subjected to large pressures, shear strain and high strain rates. The model attempts to include the phenomena encountered when brittle materials are subjected to load and damage, and is one of the most widely used models when ...
