Deborah Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Deborah Number = Time of Relaxation/Observation Time
De = t_c/t_p
This formula uses 3 Variables

Variables Used

Deborah Number - Deborah Number is the ratio of fundamentally different characteristic times.
Time of Relaxation - (Measured in Second) - Time of Relaxation is the time required for the stress-induced, by a suddenly applied reference strain, to reduce by a certain reference amount.
Observation Time - (Measured in Second) - Observation Time is a characteristic time of the deformation process.

STEP 1: Convert Input(s) to Base Unit

Time of Relaxation: 36 Second --> 36 Second No Conversion Required
Observation Time: 28 Second --> 28 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

De = t_c/t_p --> 36/28

Evaluating ... ...

De = 1.28571428571429

STEP 3: Convert Result to Output's Unit

1.28571428571429 --> No Conversion Required

FINAL ANSWER

1.28571428571429 ≈ 1.285714 <-- Deborah Number

What are Viscoelastic Materials?

Polymers are viscoelastic materials, meaning that they can act as liquids, the “Visco” portion, and as solids, the “elastic” portion. Description of the viscoelastic properties of materials generally falls within the area called rheology. Determination of the viscoelastic
behavior of materials generally occurs through stress/strain and related measurements. Whether a material behaves as a viscous or an elastic material depends on temperature, the particular polymer and its prior treatment, polymer structure, and the particular measurement or conditions applied to the material.

How to Calculate Deborah Number?

Deborah Number calculator uses Deborah Number = Time of Relaxation/Observation Time to calculate 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.

How to calculate Deborah Number using this online calculator? To use this online calculator for Deborah Number, enter Time of Relaxation (t_c) & Observation Time (t_p) and hit the calculate button. Here is how the Deborah Number calculation can be explained with given input values -> 1.285714 = 36/28.

FAQ

What is 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 and is represented as De = t_c/t_p or Deborah Number = Time of Relaxation/Observation Time. Time of Relaxation is the time required for the stress-induced, by a suddenly applied reference strain, to reduce by a certain reference amount & Observation Time is a characteristic time of the deformation process.

How to calculate 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 is calculated using Deborah Number = Time of Relaxation/Observation Time. To calculate Deborah Number, you need Time of Relaxation (t_c) & Observation Time (t_p). With our tool, you need to enter the respective value for Time of Relaxation & Observation Time and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
