Constitutive acoustic-emission elastic-stress behavior of magnesium alloy [PDF]
Repeated laoding and unloading of a magnesium alloy below the macroscopic yield stress result in continuous acoustic emissions which are generally repeatable for a given specimen and which are reproducible between different specimens having the same load

Study of Work-Hardening Rate Transient of AISI 409 Stainless Steel Under Strain Path Changes [PDF]
Materials ResearchMetal forming processes present many changes in the strain path necessary to obtain the dimensions and shape of a metal part. The loading mode, the amount of prestrain, the initial state of a material and its respective substructural arrangements affect ...

Bauschinger effect and coercivity in dual-phase steels
Chinese Physics Letters, 1984 Initial flow stresses and coercivities during and after tension and tension plus compression in ferrite-martensite dual phase steels have been measured. It was found that both parameters for tension plus compression are smaller than those for tension only. For the flow stress, this phenomenon is called Bauschinger effect.

Strain based design considerations for spiral welded pipelines [PDF]
, 2012 Pipelines are constructed in hostile environments where the occurrence of imposed plastic deformations can necessitate a strain based design approach. Under such conditions not only the strength and toughness properties have to be considered; also the ...
