Three equal laminates identified as 1 2 and 3 each of them with ten layers 0 θ θ 45 45 s and total thickness t 4 mm form the cross section. This paper presents a multistable variable cross section laminate mvcl which is designed by applying the displacement constraint at the two opposing ends of the laminate.

This paper aims to perform optimal design of cross section properties of thin walled laminated composite beams. The material properties are e 1 140 gpa e 2 10 gpa ν 1 2 0 3 and g. A theoretical model describing the mvcl as rigid bars. Stresses on transformed section 1.

Effective modulus of the upper flange lower flange and. To obtain the stress σ 2 at a x. The i beam is made from flat laminates that can have different properties. Due to this fact microscopic characterisation of composite laminates has an inherent section bias where one cross section is not necessarily an accurate representation of the complete sample.

These properties are expressed as integrals based on the cross section geometry on. Composite beams with i cross section are regarded as thin walled open section orthotropic beams.
