Numerical simulation of three-point bending tests : two distinct approaches
, 2012 In this work are presented and discussed the numerical simulations carried out for indirect tensile tests of steel fibre reinforced self-compacting concrete specimens. The post-cracking behaviour was modelled with two distinct approaches. Within the scope of the first one, the s-w relationships were obtained by an inverse analysis procedure up to ...

Verification of a displacement model for three-point bending test
Procedia Structural Integrity, 2023 Three-point bending is an important test for various parameters in materials science, and the complete test yields a force- displacement diagram. In this work, we have developed a numerical model that can describe the testing process and help us to determine relevant material properties related to the fracture process.

The parameter estimation from three-point bending tests [PDF]
, 2022 We would like to use an inverse procedure to determine the two parameters of the model using the recorded experimental data. The recorded parameters must describe the experiment completely and unambiguously. In the case of three-point bend- ing tests, the complete set of recorded data includes force, displacement, and CMOD values. Our work compares the

Three-Point Bending Tests of Zirconia Core/Veneer Ceramics for Dental Restorations [PDF]
International Journal of Dentistry, 2013 Introduction. The mechanical strength and the surface hardness of commercially available yttrium-doped zirconia were investigated. Furthermore, a comparative study of eight different ceramic veneers, to be used for the production of two-layered all-ceramic restorative systems, was carried out.Materials and Methods. Four types of zirconia specimens were

Three-point bending tests-Part I: Mathematical study and asymptotic analysis
Mathematical Methods in the Applied Sciences, 2011 The goal of this work is to study the static behaviour of a three-dimensional elastic beam when is subjected to a three-point bending test. In the rst part, under suitable compatibility conditions on the applied forces and on the geometry of the beam, we will prove the existence of a unique solution for the associated contact elastic problem; these ...

Damage formation, fatigue behavior and strength properties of ZrO[2]-based ceramics [PDF]
, 2011 It is suggested that a non-destructive testing technique using a three-dimensional X-raytomography be applied to detecting internal structural defects and monitoring damage formation in a ceramic composite structure subjected to a bending load.
