A new algorithm for self‐adaptive stress analysis is presented. The algorithm is based on h ‐convergence and uses the measured stress convergence rate as an error indicator. A theoretical relation between stress convergence rate and pointwise error of stresses is derived for both the 1‐D and 2‐D case. Some examples are presented to illustrate the behaviour of the algorithm.
