Modeling of Compression Experiments on Slender Specimens

On the basis of the model developed in Chapter 5, the temperature-dependent B-modulus, E(T), determined by Eq. (5.6) normalized by the value at ambient temperature (glassy state), E, is calculated as  

The temperature-dependent Euler buckling load Pg(T) depended on the temperature-dependent bending stiffness EI(T), as demonstrated by Eq. (7.12). Owing to a symmetric laminate architecture, the neutral axis was always located at mid-depth, and therefore, the moment of inertia, I, was temperature-independent and the specimen stiffness could be determined as
