Dear gents,

In CII databese about EN13480 materials, which is the code used for the determination of Elastic modulus and expansion coefficient?

Thanks
Best Regards

Hello Miotti

In EN13480 the Elastic Modulii and coefficients of the Thermal Expansion are determine using formlulae. The formulae are actually polynomials, and constants of the equations are set out for each material group. The independant variable of the formula is the temperature t. Each formula looks like this:

E(or Alpha) = a0 + a1*t + a2*t^2 + a3*t^3...... etc.

The values of a0, a1, a2 etc., are given in a table for each material group.
