Compressive strength is the ability of a material to resist being crushed.Compression is the opposite of tension with respect to the direction of the applied load.Most metals have high tensile strength and high compressive strength.However,brittle materials such as cast iron have high compressive str...
Based on the structure feature, a simplified structure model of high porosity metals with three-dimensional reticulatea structure has been established, which is the octahedron model. Furthermore, formulas for approximately calculating the tensile strength of these materials have been derived, and the ca...
with respect to the direction of the applied load.Most metals have high tensile strength and high compressive strength.However,brittle materials such as cast iron have high compressive strength but only a moderate tensile strength.Bending strength is that quality which resists forces from causing a ...
Theoretical tensile strengths calculated by atomistic simulations of ablation and spallation using micron-sized films agree well with experiment. Elastic-plastic response of metallic films to shock compression investigated by both experiment and theory/modeling will also be discussed. 展开 关键词: ...

When the notch-sensitivity of a metal part is low, it is evident that a part of thick cross section can be peened very effectively with high impact. I have found by extensive fatigue tests of soft steel, say 20 to 30Rc (Rockwell) that the fatigue strength of such a component increases...
Both weld metals had a high tensile strength (more than 950 MPa) and more than 17% elongation; however, their values of toughness deviated greatly, with a difference of approximately 40 J at 50°C. Analysis of the morphologies of the fracture surfaces and secondary cracks further revealed the...
Tensile strains in metals are associated with large adhesion strength. • Nucleation of Zr and Ti on AlN proceeds with larger energy decrease than Al and Cu. Abstract Devices based on AlN generally require adherent and strong interfaces between AlN and other materials, whereas most metals are kn...
The two parts of each guide are provided at their adjacent edges with interlocking fingers which are arranged to prevent a workpiece passing between the parts during oscillation of the arms. A disc roller 24, forming part of the upper guide, is driven by a belt 27 and may be provided with...
Significance: The present study showed a significant correlation between diametral tensile strengths and bond strengths. It is suggested that the use of glass ionomers with high mechanical strength is an important factor of enhancing the adhesion to metal surfaces.Yasushi...
