Calibration of viscoelastic material model using load-depth indentation data
I have the time, indentation depth, and load data of a viscoelastic material from an indentation test. The goal is to understand the local behavior of the viscoelastic material (unlike the bulk behavior that is recorded from a DMA test).
While using MCalibration, which "Load Case Type" should be selected? Also, how to select the relevant material model for calibration? I wish to use the calibrated data for an ABAQUS/Standard simulation.
You can analyze that data using MCalibration if you use one of the following load case types: "Abaqus Inverse Solver" or "General Inverse Solver". I created one tutorial about the Abaqus inverse solver option: https://polymerfem.com/mcalibration-tutorial-abaqus-inverse-calibration/ .
It is difficult to say what the problem is without more info.
Can you provide the mcal-file?
Sure. Please find the .mcal file attached herewith.
