We develop a two-stage computational method to assimilate linear viscoelastic material functions (LMFs), viz., stress relaxation modulus, creep compliance, and the complex modulus, by inferring a consensus discrete relaxation spectrum (DRS) that simultaneously fits all three LMFs. In the first stage, the DRS corresponding to the different LMFs is deduced independently, before they are combined heuristically to generate an initial guess for the consensus DRS.
