How materials can fail due to Creep

Creep is time-dependent plastic deformation. Like crack growth rate, the creep strain rate has three regions: primary, secondary (steady-state), and tertiary. Creep depends on constants, stress, activation energy, and temperature.

Man, this is seriously a good class. I like how this guy's videos are clear and to the point.

I am a high school student looking to investigate the effect of stress on steady state creep rate. Would a graph of ln(strainrate) against ln(σ) produce a straight line with gradient n? And what would be the significance of the value of n in real life applications of creep? Would greatly appreciate a reply. Thanks

Thanks for the video! I'm still a little confused - why does a high temperature mean shorter creep? Is this because the heated atoms move very fast, causing the material to break faster than when they are cooled down?

Could you provide pdf of your lectures?
