Which description correctly explains the plastic behavior of an object? temporary deformation of an object due to external force melting of an object due to external force permanent deformation of an object due to external force vibration of an object due to external force
isn't it permanent deformation of an object? I'm assuming this is intro material science and engineering
temporary deformation of an object shows elastic behavior permanent deformation of an object shows plastic behavior to understand the difference look on this link< https://www.google.co.in/imgres?imgurl=http://www.pt.ntu.edu.tw/hmchai/Biomechanics/BMmeasure/StressMeasure.files/StressStrainCurve.jpg&imgrefurl=http://www.pt.ntu.edu.tw/hmchai/Biomechanics/BMmeasure/StressMeasure.htm&h=298&w=420&tbnid=PsKYIxuVzhJyZM:&docid=OuDrFPE3aCZJ5M&ei=ZyrkVrD9E5eRuATb-LGoCA&tbm=isch > melting is a phase change phenomenon vibration refers to the oscillating state of an object
