Hello Everyone,
I have Time Domain DMA data of rubber i.e. loss modulus and storage modulus varying with time with constant 1 hz frequency. I need to convert it into prony coefficient. I need to input the coefficient into abaqus. But i am not able to get exact procedure how to convert it into the prony coefficient. Can anyone please help me with it? It would be helpful if anyone share excel sheet or matlab code for same.
Thank you
One option is the one in my paper: https://doi.org/10.22201/fi.25940732e.2020.21n2.014
This file is not by Tod Dalrymple, but I reviewed it and it looks well formulated for time-domain data, if you want you can add more terms based on the term formulation it already contains, however, you must formulate the target cell which contains the difference between the experimental data and the predicted data, when performing the least-squares regression (solver) you must change the g_i's and Go
