The variational‐asymptotic formulation for the edge layer problem is implemented by mixed‐hybrid finite elements. This approach is used to analyse the stress singularity at the free edge in composite laminates. Results indicate that the stress singularity (as r → 0) is very closely approximated by log r instead of r −α .
