Ideally, full stress-strain curves at a wide range of strain rates are available for identification of the different parameters of these models. Dynamic tensile tests are needed to produce the experimental input data. However, especially for brittle materials, data acquisition during these tests ...
stress-strain curvestrain hardeningelastic deformationA test method procedure for constructing stress-strain curves by indentation of brittle and low plastic materials under temperature ranging from 20 to 900°C was developed recently by Yu. Milman, B. Galanov et al. According to this test method ...

The derivation of the equations used to calculate the maximum tensile stress resulting from this type of loading is based on the concepts used in elementary strength of materials. The last method involves inducing tensile stresses somewhere within a body using an external compressive load. Normally,...
Brittle materials will have a small strain to failure and corresponding low toughness, while ductile materials will have a large strain to failure and corresponding higher toughness. One measure of toughness is the area under the stress–strain curve, which can be calculated by integration as ...
In order to utilize high-performance, but brittle conventional materials in flexible electronics, we propose a novel flexible substrate structure with a low-modulus interlayer. The low-modulus interlayer reduces the surface strain, where active electronic components are placed. The bending results with ...

The use of chevron-notch specimens for determining the plane strain fracture toughness (K sub Ic) of brittle materials is discussed. Three chevron-notch specimens were investigated: short bar, short rod, and four-point-bend. The dimensionless stress intensity coefficient used in computing K sub Ic...
Next, the fracture of face-centered cubic (FCC) and hexagonal close packed (HCP) single crystals was modeled, comparing the impact of crystal orientation on the stress–strain curve. Third, fracture in an HCP bicrystal was simulated and the impact of crystal orientation on the crack paths and...
For a linear elastic material the load-displacement (stress–strain) response in tension is a continuous linear rise to peak load followed by prompt fracture. The load-displacement curve for a quasi-brittle material is characterised by the following: (1) a non-linear rise to peak load; (2)...
