tension specimens were examined by conducting constant stress intensity range fatigue tests on a 2024-T3 aluminum alloy over a range of crack lengths from 0.5 to 15 mm [corresponding to crack length-to-specimen width ratios (a/W) of about 0.02 to 0.5] in dry oxygen at two Delta K levels...
Different Causes of Strain in Materials? The application of mechanical forces, such as tensile, compressive, and shear forces, mainly causes strain. Another factor is temperature fluctuation, which causes materials to expand or contract due to heating or cooling, inducing strain. Environmental factors...
Strain is a crucial measure of materials deformation for evaluating and predicting the mechanical response, strength, and fracture. The spatial resolution attainable by the modern real and reciprocal space techniques continues to improve, alongside the ability to carry out atomistic simulations. This is...
The strength of materials depends on the rate at which they are tested, as defects, for example dislocations, that move in response to applied strains have intrinsic kinetic limitations1–4. As the deformation strain rate increases, more strengtheni
A trough of low pressure over hilly areas brought heavy thunderstorms overnight. Our hilltop house lookedgrimand dreary in the rain. tension : 多指因关系不好或其它原因而出现的紧张状态,也指某物被过度伸展的程度或状态。 The w...
Strength of materials Peter A. Claisse, in Civil Engineering Materials, 2016 2.4 Strain In engineering, strain is not a measure of force, but is a measure of the deformation produced by the influence of stress. For tensile and compressive loads: (2.5)Strain= Increase in length xOrig...
The dependence of strain rate on deformation strength was investigated on various pre-strained specimens of carbon steels under plane strain. The strain rate was from 4×10-3 to 2×104sec-1. In the range of high strain rate, a newly developed Stress-Strain Curve Direct View Device was used...
Microstructure based prediction of strain hardening behavior of dual phase steels In the automotive industries, dual phase (DP) steels have increasingly used for various car body parts due to their excellent combination of high strength ... S Sodjit,V Uthaisangsuk - 《Materials & Design》 被引...
The strain-rate insensitivity of hardness indicates that the room-temperature strength of these alloy films is dominated by an athermal, strain-rate-insensitive component. The hardness of the films was found to be in the range of 2.4 to 3.3 GPa, depending on grain size....
