Stress/Strain Distribution
Directional Elastic Properties (Polar Moduli)
This polar plot shows the variation of equivalent Young's Moduli (Ex, Ey) and Shear Modulus (Gxy) in GPa as a function of orientation angle θ (0° to 360°). The plot updates dynamically as you modify the laminate stacking sequence in the editor or the material properties.
Optimizer Constraints
Lamination-parameter mode requires exactly one candidate material.
Requires strength ratios to be greater than SF (i.e. Failure Index ≤ 1/SF).
Requires "Direct Stacking GA" strategy. Material/thickness selection still comes from the candidates below; only the angle becomes a free variable. The 10% Rule is skipped in this mode.
Weibull Statistical Parameters
Indicates scatter of strength. Typical value for carbon/glass fibers: 8.0 - 15.0.
Allowed failure risk (e.g. 0.01 = 1% chance of FPF).

The Failure Coefficient (Scale parameter) represents the load factor multiplier at which the probability of laminate failure reaches 63.2%. The algorithm calculates the exact strength limit of the laminate system (using a Monte Carlo simulation or evaluating directly against the loaded experimental coupon data).
Experimental Test Data Fit
Upload a CSV or TXT file with experimental failure/strength measurements (one value per line or comma-separated) to fit a Weibull distribution and overlay it on the chart.
