The proposed model will now be used to simulate a suite of conventional brittle creep experiments under different constant applied differential stresses (i.e. “Behavior of type K-8 glass under in dynamic compression and subsequent unloading,”, Kanel, G.I., A.M. Molodets, and A.N. Materials that do not fail in a ductile manner will fail in a brittle manner.Brittle fractures are characterised as having little or no plastic deformation prior to failure.Materials that usually fracture in a brittle manner are glasses, ceramics, and some polymers and metals.

Brittle failure limits the compressive strength of rock and ice when rapidly loaded under low to moderate confinement. (1983). Are brittle materials elastic? (1978). Grady, D.E. The criterion is based on the classical Mohr-Coulomb limit condition in which a friction tensor is involved. The reason for the difference in behaviour is that in brittle materials, crack growth predominates over plastic flow as the yield mechanism. David J. The Karagozian and Case concrete (KCC) model was exploited as the material constitutive law and a new method to utilise this model for efficient and accurate simulation … Macroscopic behavior. Behaviour of brittle materials under dynamic loadings, experimental approaches and modelling from 01/09/2010 to 13/09/2019 Thèse. Mintsev, S. Bless, and C.H.M. It is known that nominally brittle materials may exhibit plastic deformation in indentation, scratching, and microcutting when the loaded region is sufficiently small. The performance of the model is tested through comparisons between numerical simulations and test data. Three typically different stress-strain behaviours can be observed in polymeric materials. “Evidence of ductile response of alumina ceramic under shock wave compression,”, © Springer Science+Business Media New York 2004, Shock-Wave Phenomena and the Properties of Condensed Matter, Institute of Problems of Chemical Physics, https://doi.org/10.1007/978-1-4757-4282-4_4, High-Pressure Shock Compression of Condensed Matter. DYNAMIC BEHAVIOR OF BRITTLE GEOLOGICAL MATERIALS UNDER HIGH STRAIN RATES M.L. Millett, and Z. Rosenberg (1996). Multilayer systems comprising brittle materials can exhibit substantially different behaviors under flexural and tensile loadings. These keywords were added by machine and not by the authors. Uniaxial Strength Behavior of Brittle Cellular Materials. In Section 2, a simple continuous damage model is proposed using a thermodynamics potential and some principles of fracture mechanics. In the previous section we have seen the effect of cracks on cleavage of brittle materials. “Analysis of shock wave structure in single crystal olivine using VIS AR,” in: Galin, L.A., and G.I. One of the characteristics of a brittle failure is that the two broken parts can be reassembled to produce the same shape as the original component as there will not be a neck formation like in the case of ductile materials. “Modes of dynamic shear failure in solids,”, Kanel, G.I., A.A. Bogatch, S.V. Senf, H., E. Strausburger, and H. Rothenhausler (1995). Brittle materials include a wide range of material classes: From polymers to metals, through classic glass, ceramics, and composites.
