Characterization of the Elastic-plastic Region Based on Magnetic Memory Effect
metal magnetic memory plastic deformation magnetomechanical effect
2011/8/3
Detecting stress concentration, especially critical stress state leading to structure damage or failure, is one of the most important tasks of equipment diagnosis.
Permeable Steel and Its Application in Plastic-Injection Mould
powder metallurgy permeable steel plastic-injection mould venting system
