I am currently doing a material characterisation project and have performed a standard tensile test on a number of 304 stainless steel specimens. I have obtained a number of stress-strain curves from the testing and have been told I need to relate them to the Ramberg-Osgood material model in...

Thanks very much!

bump. Anyone get any help on where I could even obtain such information?

what is n in the equation pv = nRT? i thought the perfect gas eqn was pv = mass * R * T also i am not given a value for the gas constant (R). if it is any help the answer that is given in the book is in kJ/kg not in J.

but i don't know any of the volumes so this method would not work

hey guys got this question that i have been stuck on for a while. air is expanded from 1M Pa at 327 degrees celcius to 200kPa in a closed piston cylinder device. for the process PV^1.2 = constant. calculate the work done in kJ/kg during this process i hav managed to work out the temperature...
