PVC sandwich core materials: Mode I fracture toughness

Composites Science and Technology, 1989
Abstract The fracture of a cracked PVC sandwich core material has been investigated. Mode I fracture toughness is evaluated using linear elastic fracture mechanics (LEFM), nonlinear fracture mechanics and a damage zone model. For the crack sizes and structural dimensions relevant to sandwich constructions, LEFM is not applicable according to the ASTM

Mode I Fracture Toughness Testing of Composite Pipes

Applied Composite Materials, 2013
A common industrial production process for axially symmetric composites is filament winding. For this type of material, interlayer properties cannot be evaluated using the available ISO and ASTM standards because the curved surfaces and partially interwoven fibers of cylindrical parts can affect the results.

Mode I Fracture Toughness of CNT‐Reinforced PMMA

Strain, 2015
AbstractThe influence of carbon nanotube (CNT) concentration on the fracture toughness of poly(methyl methacrylate) (PMMA) was examined on single‐edge V‐notched‐beam (SEVNB) specimens. Six groups of SEVNB specimens containing 0.5, 1, 2, 4, 8.5 wt% of CNTs and neat PMMA as a reference were tested.

Mixed mode (I+II) fracture toughness of polymer nanoclay nanocomposites

Engineering Fracture Mechanics, 2013
Abstract In this work the mixed mode fracture behaviour (I + II) of an epoxy/nanoclay nanocomposite system is analysed, discussing the results from Single Edge Notch Bending tests. It is found that nanomodification significantly enhances the fracture toughness of the epoxy resin on the entire range of mixed mode loadings (from pure mode I to pure ...

Size and Geometry Effects on Rock Fracture Toughness: Mode I Fracture

Rock Mechanics and Rock Engineering, 2013
In this paper, the effects of specimen size and geometry on the apparent mode I fracture toughness (K c) of an Iranian white marble (Neyriz) are studied. A number of fracture tests were conducted on center-cracked circular disk (CCCD) specimens with different radii to investigate the size effects on K c. The experimental
