It is known from the literature that elastic plastic porous materials under strain controlled cyclic loading show an increase of void volume fraction called void ratchetting effect.
The behaviour of typical armour steel material under large strains, high strain rates and elevated temperatures needs to be investigated to analyse and reliably predict its response to various types of dynamic loading like impact.
In the case of a solid composed of many particles a magnitude of the average bond energy – the failure energy – exists, which limits the energy that can be accumulated in an infinitesimal material volume under strain.
The dynamic test results of two metal materials under strain-rates of 10, 100 and 200 showshow that the sensor is effective for reducing system ringing.
Then, the dynamic compressive properties of RCC material under intermediate strain rate are investigated in terms of failure pattern, stress-strain curve, dynamic increase factors (DIF) of compressive strength, Young's modulus and critical strain at peak stress.
However, a detailed picture of the behavior of the material under high strain rates can only be gained by treating each of its components independently.
To investigate mechanical properties of PVB material under different strain rates and different temperatures, a series of tensile tests on 1.52 mm-thick PVB specimens are carried out, covering designed engineering strain rates from 0.1/s to 300/s and temperatures from −30 °C to 40 °C, using an Instron high-speed servo-hydraulic testing machine and temperature box.
This benchtop validation study tested the feasibility of using the UVE system by measuring the mechanical properties of a tissue-mimicking material under large strains.
Along with the rising application of high strength steel in civil engineering practice, it has become imperative to gain comprehensive understanding of the elastic and plastic behaviour of these materials under given strain or stress histories.
The proposed model is validated with experimental data from literature through testing four metal materials under various strain paths with zero/non-zero mean stress.
