Hi Dr Jorgen,
I am trying to calibrate the Three Network Viscoplastic (TNV) model for an anisotropic thermoplastic composite material system.
I am using the following models for individual networks:
Network A and Network B - Yeoh hyperelasticity with power law flow
Network C - HGOB hyperelasticity
Besides the default upper and lower bounds are there any other constraints that I should put on material parameters while calibrating the model? For example in Three Network Model flow resistance of Network A < that of Network B.
I am trying to understand if these networks are interdependent.
Also, can I use any combination of available models?
