RT Journal Article T1 Numerical simulation of dynamic TPB fracture test in a modified Hopkinson bar A1 Loya Lorenzo, José Antonio A1 Fernández Sáez, José A1 Navarro Ugena, Carlos AB Dynamic three point bending fracture tests performed in a modified Hopkinson Bar are used to obtain material fracture properties (such as the fracture-initiation toughness) at high strain rates. This work presents a three-dimensional numerical analysis of the aforementioned tests, performed by the Finite Element Method, implemented in the commercial code ABAQUS. The relationship between the Stress Intensity Factor and the Crack Mouth Opening Displacement was examined and compared with the bidinensional one, The results indicate that the use of 2D plane strain solutions can underestimate the fracture properties.
