    Exploring the Fate of Energy in Plastic Deformation of Materials

    I think I'm starting to see it. When the atoms scramble to find the lowest energy state after plastic deformation, heat is created which increases the entropy of the system. Additionally, by breaking bonds in the lattice structure, the entropy of the system has also been significantly...

    Exploring the Fate of Energy in Plastic Deformation of Materials

    Thanks again for the reply. I suppose I'm basically stumped on how (on the atomic scale) deforming material consumes energy. I understand how heating an object results in increasing the RMS velocity of its constituent atoms as well as how compressing a gas increases its pressure and...

    Exploring the Fate of Energy in Plastic Deformation of Materials

    So in other words, 100 kJ of heat is created when 100 kJ of energy is spent bending a bar? E = 100 kJ, Q = 100 kJ, and W = 0 kJ? I'll have to read more on hysteresis as well. Thanks for the reply.

    Exploring the Fate of Energy in Plastic Deformation of Materials

    I have a simple question that I cannot find a compelling answer for. If I expend (let's say) 100 kJ bending a steel bar into a right angle, where did the energy go? Some will obviously be expended as noise and heat. Will the rest be expended in the plastic deformation of the bar? No useful...
