Overall properties of anisotropic materials containing cracks

Frictional energy dissipation in materials containing cracks

Kachanov’s simplifiedmodel ofmicrocrack interaction is applied to an investigationof the behaviour of a cracked body under predominantly compressive periodic loading, so that the cracks experience periods of closure and slip, with frictional dissipation. The model is shown to be equivalent to a discrete elastic frictional systemwith each crack representing one node. Theorems and algorithms from...

Explicit relations between elastic and conductive properties of materials containing annular cracks.

The impact of annular cracks on the effective elastic and conductive properties of a material is analysed. The compliance contribution tensor of an annular crack - the quantity that determines the increase in compliance of a solid due to introduction of such a crack - is derived analytically. The resistivity contribution tensor of an annular crack is calculated numerically. It is shown that an ...

A Theoretical Study of Wall Ironing for Anisotropic Workharden Materials

Bridged interface cracks in anisotropic bimaterials

The bonding strength between dissimilar materials in composites is often relatively weak. Interface debonding and cracking are of common occurrence. As an e€ ective method to minimize such failures, ® bre stitching is used to enhance the bonding strength when joining layers in polymer composites. With the presence of the reinforcing ® bre, the overall elastic response for each component of the ...
