The compressive strength of the material would correspond to the stress at the red point shown on the curve In a compression test, there is a linear region where the material follows Hooke s lawHence, for this region, =, where, this time, E refers to the Young s Modulus for compressionIn this region, the material deforms elastically and returns to its original length when the stress is removed...

A parameter which is employed to group these columns is the slenderness ratio, L e / k The minimum slenderness ratio Le k min marks the nominal transition from crushing to buckling If the axial stress, σ , is plotted as a function of slenderness ratio, then the minimum slenderness ratio is the nominal transition from the constant stress for ....
