Impact response of tough carbon fibre composites

Composite Structures, 1989
Abstract The impact damage response of new tough carbon fibre composite systems was investigated. The low velocity impact damage tolerances of crystalline thermoplastic and toughened epoxy matrix composites are compared and contrasted for two different stacking sequences and target geometries.

Informativeness of measurements of impact toughness

Metal Science and Heat Treatment, 2008
Measurements of the geometry of a specimen and a fracture are a useful supplement to measurements of the impact toughness and are more reliable than the determination of the “fraction of the ductile component.” Optimum (with respect to the maximum likelihood principle) estimation of the reliability of the shift of serial curves of impact toughness and ...

Phenomenological Modelling of Impact Toughness Transition Behaviour

Applied Mechanics and Materials, 2015
The toughness transition behavior of ferritic steel results from the fact that two competing fracture mechanisms can be activated independently or progressively. Temperature, strain rate and the material ́s hardening properties are the major influences affecting the result of this competition between cleavage and ductile fracture mechanisms. An elastic

Improved impact toughness of stainless chromium steel

Metal Science and Heat Treatment of Metals, 1962
1. Quenching from 1100 to 1200°C, followed by water or air cooling and cold plastic deformation by 30 to 40% at temperatures within the 200 to 600°C range and 850 to 900°C annealing for 90 to 120 min with rapid cooling, enhance impact toughness at room temperature In 1Kh16S2MB2 steel, raising it from 1–1.5 to 10–11 kg/cm2 and to 11.2 and 19 kg/cm2 ...

Impact Toughness of Closed-Cell Aluminum Foam

Materials Science Forum, 2018
The impact toughness of closed-cell aluminum foam with various densities was investigated. The impact load history revealed an elastic region followed by a rapid load drop region. The peak load and impact toughness of aluminum foam increases exponentially with density.

Notch Impact and Fracture Toughness Testing

1992
When an external stress is applied to a material, the material will be deformed, or strained. If the magnitude of the stress is increased, the material will eventually fail by fracturing. Not all materials fail in the same manner, and the type of fracture that occurs may be either brittle or ductile.

Impact Fracture of a Tough Ductile Steel

1990
The impact fracture of a tough ductile material is examined by comparing the results of static and dynamic viscoplastic finite element computations with experimental observations of the crack tip opening displacement (CTOD) during static and dynamic (impact) fracture.
