Abstract
The influence of topcoat–bondcoat interface roughness on thermo-mechanical stresses is of high relevance for understanding the failure mechanisms as well as assessing the lifetime of TBCs. Analysing the effect of interface roughness on stresses could be a tedious and extremely complicated task to perform experimentally. Therefore, numerical modelling techniques are commonly used to understand these fundamental relationships. In most of the earlier works, a 2D or 3D sinusoidal wave profile has been chosen as a simplification to represent the topcoat–bondcoat interface [1–16] to analyse the stress distribution in TBCs.
