SS-V: 8000 Laminated Strip

Test No. VC01Find the deflection, bending and shear stresses in a simply supported laminated strip.

Definition

The material properties are:

Properties: Value
$E x$: 1e5 MPa
$E y$: 5e3 MPa
$v_{x y}$: 0.4
$v_{y z}$: 0.3
$G_{x z}$: 2e3 MPa
$G_{y z}$: 2e3 MPa

v_{x y} / E x = v_{y x} / E y

Boundary Conditions

One quarter of the beam is modeled
Sliding constraints are applied at X=25mm and Y=5mm
Displacement in Y and Z are set to 0 at A
Load of 25 N is applied on the edge at E
