Abstract: This paper proposes a new and less laborious version of the size-effect method for measuring the fracture energy or fracture toughness of concrete as well as other nonlinear fracture characteristics, such as the effective ...

Abstract: In-plane dynamic fracture jumps and acoustic emissions in sea ice floes of different sizes are simulated by the particle system. Fracture patterns and time sequences similar to those observed in experiments are achieved. ...

Abstract: The modulus of rupture of concrete, which characterizes the bending strength of unreinforced beams, is known to depend on the beam size. Because there is no large stable growth of a crack before the maximum load is reached, ...

Abstract: Test results on the size effect in the pullout strength of reinforcing bars embedded in concrete are presented. Attention is focused on failures due solely to interface slip, with no cracking in the surrounding concrete. ...

Abstract: Measurements of the size effect on the nominal strength of notched specimens of fiber composite laminates are reported. Tests were conducted on graphite/epoxy crossply and quasi-isotropic laminates. ...
