Necking, in engineering or material sciences, is a modality of tensile deformation where comparatively huge quantities of strain focalize disproportionality in a tiny region of the material. The ensuing salient decrease in the local cross-sectional area furnishes the basis for the name “neck”. Mul...
In this context, a quantity called strain is defined as being the relative change in the dimensions of the body under study and has a non-dimensional value. The deformation of a body caused by a force (in this case, axial) can be quantified with the physical quantities stress and strain....
Simplified Formula for Tensile Strain of Buried Pipeline Subjected to Lateral Spreading due to Soil LiquefactionThe lateral spreading due to the soil liquefaction induced by an\nearthquake causes a large deformation of buried pipelines and leads to\naxial pipe strain, which may result in failure. ...
The tensile strength Rmis calculated by the formula: Rm=FmaxS0,MPa where:Fmax- maximum force (load required to break the sample) [N],S0- initial area of the measuring part of the test sample [mm2]. Young׳s modulus of elasticityErepresents the ratio between stress σ and strain ε (pr...
The engineering stress–strain tensile behavior of mild steel is shown in Fig. 7-4. At low applied load levels stress varies linearly with strain, and the proportionality or slope of the line (i.e., Δσ/Δe) in the elastic regime yields Young's modulus, E. The response is reversible...
The formula for tensile strain remains the same, but compressive strain becomes a change in length multiplied by original length. The formula for compressive strain remains the same, but tensile strain becomes a change in length multiplied by original length. ...
Materials loaded with tension are subjected to stress concentrations at the location of material defects and abrupt changes in geometry that accelerate the strain of the material. Some materials may exhibit ductile behavior and can tolerate a certain number of defects before failure, while brittle mate...
Although these types of specially designed in situ straining TEM holders can provide quantitative stress–strain data, it is very difficult to use them for two-dimensional HRTEM imaging for the investigation of atomic-scale deformation mechanisms because the holders are usually single-tilt. Sign in ...
The platform was applied to human cardiomyocytes (AC16) under cyclic strain (5%, 10%, 15%, 20 and 25%), and we found that cyclic strain promoted cell growth induced the arrangement of cells on the membrane to gradually unify, and stabilized the cells at 15% amplitude, which was even ...
