or we must make the component large enough so that the applied force produces a stress that is below the yield strength. In contrast, the tensile strength is relatively unimportant for ductile materials selection and application since too much plastics deformation takes place before it is reached....
A new plane stress yield function that well describes the anisotropic behavior of sheet metals, in particular, aluminum alloy sheets, was proposed. The anisotropy of the function was introduced in the formulation using two linear transformations on the Cauchy stress tensor. It was shown that the ...
Aluminum honeycomb, due to its high and relatively constant crush strength over large strains, is frequently used as an energy absorbing material for protecting sensitive packages during accidents or in high-speed impactenvironments. To measure the crush strength at high crush...
The grain size dependence of the yield stress of an Al-Al4Ca alloy with microduplex structure is investigated. A model for its interpretation is proposed in which the critical mechanism for the occurrence of macroscopic yielding is the nucleation of dislocations at the Al/Al4Ca interfaces. The ...

yield stress/ AA6111 aluminum alloyIn this work, a series of aging treatments has been conducted on AA6111 alloy samples for various times at ambient temperature (so-called natural aging) and at temperatures between 60 and 180掳C (artificially aged). The time at artificial ageing was chosen ...
of intersection of the parallel line to the stress-strain curve. The proportional limit, elastic limit, and yield strength are defined differently; but their values are fairly close to each other in many cases. Yield strength cannot be measured for brittle materials such as composites and ...
