Abstract This paper presents an analytical solution to the non‐uniform pressure on thick‐walled cylinder. The formulation is based on the linear elasticity theory (plain strain) and stress function method. As an example, the proposed solution is used to model the stress distribution due to non‐uniform steel reinforcement corrosion in concrete. The model is formulated considering different scenarios of corrosion pressure distribution. It is validated against the finite element model for different cases of non‐uniform pressure distributions. The results show that the corrosion‐induced cracks are likely to start just beyond the anodic zone. This is confirmed by the experimental tests on concrete cylinder exposed to non‐uniform accelerated corrosion of steel reinforcement. The model can be effectively used to calculate the distribution of corrosion‐induced stresses in concrete.
