How to Evaluate Deborah Number?

Deborah Number evaluator uses Deborah Number = Time of Relaxation/Observation Time to evaluate the Deborah Number, The Deborah Number formula is defined as the ratio of the time it takes for a material to adjust to applied stresses or deformations, and the characteristic time scale of an experiment (or a computer simulation) probing the response of the material. Deborah Number is denoted by De symbol.
