I`m working on liquefaction resistance of sand utilizing shaking table tests.

i want to draw shear stress-strain curves for each test and i need help from you,my Physicist colleagues. my model container is 200*70*50cm and i`ve put acceleration transducers at depth 7,21 and 35cm from top.I have a general idea of how i can draw shear stress-strain curves using time history of acceleration but i`m not sure about it.i would be more than happy if you can help me.

I guess for determining shear stress at any point i can use t=sigma miai from top to the point of interest.which t is shear stress ,mi is mass at any point and ai is acceleration at any point.and i simplify the process by assuming acceleration is linear through depth.am i right about the process? and i`m so confused how i can determine shear strain at any depth.

i would appreciate your help
