Creep Calculation

  1. Dec 12, 2011 #1
    Hi all, new to the thread due to a lab report being in tomorrow!

    Basically if anyone could shed some light on how to calculate secondary creep..
    In uni we have undertaken a lab report on tin/lead solder and given two formulaes to calculate the ε.

    ε = αlnt + c
    ε = βt^m + c

    Temperature constant at 23°C
    mass of 2kg used

    ive plotted the extension vs time graphs on excel but now stumped where to go due to never coming across this field in uni.

    Any help is greatly appreciated and if any other information is needed feel free to ask.

    Thanks all, Dan
