#16 Conveyor Belt Modulus of Elasticity - Pooley Inc.

To use the elastic modulus value in determination of how much belt stretch might be expected, it is common to divide the belt modulus into the conveyor operating tension. For example, a belt with a modulus of 5000 piw operating at 200 piw would be expected to elongate by 4.0 percent........ 200 / 5000 = .04

Conveyor belt stretch: The increase in belt length which takes place when tension is imposed. Stretch is either elastic or permanent. Elastic stretch is a temporary change in length which varies directly with the pull. Permanent stretch is the residual change in length after tension has been removed; it generally accumulates over a period of time.
