The buckling mode can be designated “elastic” or “plastic” depending on the value of SZZ relative to the yield stress at the onset of buckling. Buckling of a column can occur in one of two modes—elastic buckling or plastic buckling.
WebOct 4, 2024 · Sheath folds are incredibly irregular. The exact term in geology is ‘non-cylindrical’: they have strongly elongated and curved hinges, like a long nose! In shear zones, they are stretched parallel to the direction of tectonic transport. Due to their complex shape, sheath folds are commonly difficult to visualize.
