    A low-velocity impact commonly is associated with the damage due to possible incidents during composite structure's lifecycle and may cause barely visible damage on impacted surface. This effect induces a problem of residual strength estimation of structure after impact, which is especially apparent on compression after impact (CAI) test. Simulation assumes an application of damage initiation criterion and damage evolution model susceptible to the different complex failure modes. It requires a comprehensive understanding of numerous failure mechanisms in composite materials and execution of complex mechanical tests for obtaining of advanced mechanical characteristics. Presented work proposes an innovative approach for residual strength estimation of composite plate after impact based on topology optimization algorithm for finding of the “worst-case” damage distribution. As special input data, it requires an estimation of impact energy distribution between different damage modes that can be obtained from experimental statistics or direct numerical simulations. The proposed approach implemented into Abaqus software and compared with experimental results.
