Flexural Creep Modulus - ISO 6602
The ratio of initial stress to creep strain after a specified time under specified conditions.
A test specimen is subjected to three-point bending under a constant force. The resulting deflection at mid-span is measured after a specified time.
The tensile creep modulus, Et, is calculated using the formula:
Et = σ/εt = L3F/4bh3st
where L is the distance between the supports (span),
F is the applied force,
b is the specimen width,
h is the specimen thickness,
and st is the specimen deflection at mid-span at a specified time.
