RT Journal Article T1 Three-point bending tests. Part II: An improved formula for the modulus of rupture and numerical simulations A1 Guitián Rivera, Francisco A1 Quintela Estévez, Peregrina A1 Sánchez Rúa, María Teresa A1 Valcárcel, V. K1 Modulus of rupture K1 Contact conditions K1 Numerical simulations AB The goal of this paper is to analyze analytical and numerically, from several perspectives, the modulus of rupture (MOR)for brittle materials, studying the bending test of three points which is normally used in laboratory to calculate it. Inparticular, we will give four different approaches to the MOR: through the classical theory of beams; by means of theone and three-dimensional numerical simulations; and by using an improved expression to the MOR obtained through itsasymptotic analysis. Finally, we will present these methodologies for cylindrical and rectangular beams made of porcelain.
