I am a M-tech student working on a project of Drop weight impact testing machine for measuring the crashworthiness of structure. As it will be a lab-scale model, the budget doesn't allow me to include load cells for measuring peak impact force by load-displacement graph.
I am planning to calculate Average impact force as per the deformation obtained in specimen but
for getting the peak impact force(Elastic response) by theoretical approach, can i use the following equation
Impact Force = W √ 2h / δst
Where W = drop weight in N
h = drop height in m
δst = deflection when that drop weight is statically applied in m
Whether this theoretical calculation instead of load cell arrangement can yield me a comparable result of peak impact force ?
