Discussion on "Interfacial Residual Stress Analysis of Thermal Spray Coatings by Miniature Ring-Core Cutting Combined with DIC Method" by J.G. Zhu et al., Experimental Mechanics DOI:10.1007/s11340-012-9640-2

In this article authors present similarities between an article by J.G. Zhu and colleagues regarding measurement of the residual stress in thermal barrier coatings (TBCs) using a self developed deformation sensor and the article regarding the same by M. Sebastiani and colleagues published in the previous issue. Topics discussed include similarity in experimental implementation, use of scanning electron microscope images, and use of micro-ring core method for thermal spray coatings.
