Symbol: Rm Unit: MPa 抗拉强度(tensile strength) 试样拉断前承受的最大标称拉应力。 抗拉强度是金属由均匀塑性变形向局部集中塑性变形过渡的临界值,也是金属在静拉伸条件下的最大承载能力。对于塑性材料,它表征材料最大均匀塑性变形的抗力,拉伸试样在承受最大拉应力之前,变形是均匀一致的,但超出之后,金属开始出现缩...

where the Einstein summation convention on repeated indices applies and δij denotes Kronecker's symbol. The principal invariants of the stress deviator J1, J2, and J3 can be calculated using eqn [58] in the Appendix but applied to the components of the stress deviator instead of the stress ...
What is the symbol for tensile stress? The tensile stress may increase up until the tensile strength limit, which is known as the limit state of stress, and is defined as the force per unit area that is associated with stretching. It is denoted by the symbolσ. ...
10 Representative hardness value (H) from nanoindentation as a function of indentation strain rate (\(\dot{{\boldsymbol{\varepsilon }}}\)) for NC NiCo alloy. The strain rate sensitivity exponent, m, was estimated to be about 0.04 from the slope of the double logarithmic line fitting the ...
NOTES: 1 When a proof stress (Rp ) is specified, the non-proportional elongation value is stated (e.g. 0.2% of the extensometer gauge length) and the symbol for the stress is followed by this value giving the prescribed percentage of the extensometer gauge length (e.g. Rp0.2 ). (See...
