Multi-side Digital Image Correlation (DIC) evaluation of CFRP bonded to poplar timber Rescalvo Fernández, Francisco José Timbolmas, Cristian Ioan Bravo Pareja, Rafael Portela, María Lorenzana, José Digital Image Correlation (DIC) Poplar timber Mixed mode I&II This work was supported by the Ministerio de Economía, Industria y Competitividad under Grants BIA2017-82650-R and PID2020-114386RB-I00 Digital Image Correlation (DIC) is a technique that permits full analysis of the strain field distribution upon the surface of solids. The nonlinear bonding interaction between poplar timber and CFRP (Carbon Fiber Reinforced Polymers) reinforcement under mixed mode I&II is analyzed. The test setup inserts an eccentric axial load and a corresponding bending moment. The experiments show strain distributions composed of two lateral transfer zones in which bonding mode II predominates and, a central zone of constant strain in which bonding mode I is dominant. The maximum load capacity increases with the bond length until the effective bond length. 2025-12-22T09:50:58Z 2025-12-22T09:50:58Z 2022-11-22 journal article Publisher version: Rescalvo, F.J., Timbolmas, C., Bravo, R., Portela, M. & Lorenzana, J.
