Abstract:

In studying the strength characteristics of pristine, soda-lime-silica glass using four-point bending, large deflections are imposed on the glass specimens. These large deflections lead to nonlinear relations between load and deflection and the assumptions of simple beam theory are no longer applicable. Without making the simplifying assumptions of simple beam theory, the nonlinear differential equation governing beam deflections in four-point bending was solved using numerical techniques. Author
