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, E_t, is calculated using the formula:
E_t = σ/ε_t = L³F/4bh³s_t
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 s_t is the specimen deflection at mid-span at a specified time.
