Composite laminate structures are prone to probabilistic catastrophic failure due to uncertainty
in material and strength properties. The Reliability Index Approach (RIA) estimates the failure
probability as a function of the reliability index and is formulated as a minimization problem.
For highly dimensional problems and discontinuous implicit structural response functionals,
gradient-based optimization methods suffer from premature local convergence, or even divergence. A new hybrid evolutionary algorithm is developed, to achieve global convergence of the RIA problem with practical efficiency.
