Laminate Cross-Section: Classical Laminate Theory (2D)

This 2D companion to the flagship 3D composite-material-layers simulation resolves the same question — how a stack of fiber-reinforced plies shares a bending load — with a genuinely different method: full classical laminate theory (CLT) rather than a single orientation-averaged modulus. Every layer gets its own fiber angle and material (carbon, glass or aramid fiber in an epoxy matrix), each ply's stiffness is derived from the rule-of-mixtures Voigt/Reuss bounds and rotated into the beam axis, and the laminate's bending stiffness is assembled ply-by-ply from each layer's distance off the mid-plane cubed — so stacking order, not just fiber fraction, changes the answer. Set the ply count, tune each layer's angle and material, dial up the center load, and watch the flexural and axial moduli, bending stiffness, deflection and peak ply stress update from the underlying CLT calculation in real time.
