Abstract:
Snapback load-deflection relations of shear failing beams are numerically obtained using Arc Length Method with Selected Displacement Control Points. Identifying stress loading area while load decreases, failure process of snapback shear failure of a beam was clarified. The fundamental understanding of the phenomena is extended to failure concept of a structure through energy balance calculation.
