An Inverse Identification Procedure for the Evaluation of Equivalent Loading Conditions for Simplified Numerical Models in Abaqus

In the finite element simulation process, it is very common to use simplified models replace original complex reduce computational cost. To improve accuracy of with numerical in Abaqus Explicit, we propose an inverse identification procedure evaluate equivalent loading conditions be applied these models. We construct objective function test correlation between final deformed shape obtained by on full and A Python program using Levenberg–Marquardt algorithm implemented optimize this function. parallel approach, a data processing step, validated dynamic tensile test, obtain more accurate responses, including extraction estimation. Full for Taylor shear were constructed Explicit FEM code. The complete then replaced models, which some non-essential parts removed boundary modified. order same results terms geometry, proposed used calculate impact velocities
