One dimensional stress,strain,deflection analysis

  1. Aug 1, 2010 #1
    i am an undergrad student

    i had an eqn like the following from which i am to find deflection,stress and strain using finite difference method

    EI (d4 y/dx4)-m(d2y/dt2)-P sin wt=0


    i have developed a matlab prog for deflection

    how can I find stress and strain now????

    i am confused which formula should i use????
    should i find moment first and then stress or is there any other way???

    just tell me the way, not the prog
