| description | A trigonometric beam theory (TBT) is developed
for the bending analysis of laminated composite and sandwich
beams considering the effect of transverse shear deformation.
The axial displacement field uses trigonometric
function in terms of thickness coordinate to include the effect
of transverse shear deformation. The transverse displacement
is considered as a sum of two partial displacements,
the displacement due to bending and the displacement
due to transverse shearing. Governing equations and
boundary conditions are obtained by using the principle
of virtual work. To demonstrate the validity of present theory
it is applied to the bending analysis of laminated composite
and sandwich beams. The numerical results of displacements
and stresses obtained by using present theory
are presented and compared with those of other trigonometric
theories available in literature along with elasticity
solution wherever possible. |
