Calculation of static bending properties from load–deflection curve of static bending test [10]. Pm, maximum load; Pp, load at proportional limit; Ym, maximum deflection; Yp, deflection at proportional limit. MOE and MOR were determined by the following equations: MOE (GPa) = Ppl3/4Ypbh3, MOR (MPa) = 3Pml/2bh2, where l is the span, b is the width of the specimen, h is the height of the specimen, bending work is an area enclosed with OBC in this graph.
