Finding Stiffness Matrices A, B, and D Step 1 of 5

This calculator constructs the [A], [B] and [D] matrices of a laminated fiber-reinforced composite. Please enter the layout information (the angle of fibers of each layer) of your laminate and click next.

Input

Layout Info
(Fiber angles)

0/60/-30/30/-60/0

Layout examples:

0^° represents the fiber direction.
[0^°/90^°₂/45^°]_s should be input as "0/90/90/45/-45" and select "S" for symmetric.

[0^°/60^°/30^°/-60^°/0^°] should be input as "0/60/-30/30/-60/0" and select "T" for total.

All angles are in degrees. Click here for unit conversion.

Note that the degree sign ° is NOT part of the input.

A slash / must be in place as the separator between layers.

'T' indicates that the input represents the fiber angles from the top layer to the bottom layer.

'S' indicates that the laminate is SYMMETRIC in both geometry and material with respect to its mid-plane.

The maximum allowable number of input angles is 100. For 'T', that is 100 layers; for 'S', that is 200 layers.
