A small amount of fibre or other material may run in other directions with the main intention being to hold the primary fibres in position although the other fibres may also offer some structural properties.
Unidirectional laminated composites.
The total thickness of the laminate is 2 mm.
In the present research the mode i r curve behavior of unidirectional laminated composites with different crack lengths and thicknesses are investigated.
A micromechanics based constitutive model incorporating damage models was proposed to model the effective elastic behavior of unidirectional laminated composites.
By knowing the absorption behavior of the unidirectional ply the behavior of laminated composites can be predicted.
By using explicit analysis crack tip speeds and elastodynamic effects are presented.
The first is the dynamic analysis of the unstable crack growth in l shaped unidirectional laminated composites under quasi static loading.
