Finite element modeling of the three-point bend impact test
Computers & Structures, 1993Abstract A dynamic finite element program has been applied to the analysis of the three-point bend impact specimen. First, the behavior of an unsupported specimen struck at its center was modeled. From this it was predicted that the best striker force response in an impact test would be obtained with an overhang at each end of 22% of the total length.

Impact Three-Point Bend Testing for Notched and Precracked Specimens
Journal of Testing and Evaluation, 1978Abstract Testing and data analysis procedures developed from a recently completed fracture toughness testing program on ferritic nuclear pressure vessel steels are presented. These procedures describe the measurement of dynamic fracture toughness at stress intensification rates near 105 MPa√m/s using instrumented impact testing of three ...

Poroviscoelastic behaviors of the shale sample in the three-point bending test
International Meeting for Applied Geoscience & Energy, 2015Summary The poroviscoelastic behaviors of the shale sample in the three-point bending test are investigated in this paper. The coupling effects of the viscoelastic relaxation (creep) of the shale matrix and the fluid diffusion are considered. Two types of test (constant load or constant deflection) are simulated, the solutions for the

Self-compacting concrete has proved itself to be a suitable solution in many scopes of construction industry. Its higher performance and better flowability has allowed considering its use in new applications. Nevertheless, the brittleness commonly associated to concrete is still present even though it may be compensated with the use of fibres.
