WebJun 20, 2024 · The present work aims to evaluate the effect of crack propagation rate on the mechanical response of a viscoelastic interface during the self-similar crack propagation regime of a DCB test. Viscoelastic interface behavior has been considered, and its influence on the DCB response has been analyzed through the comparison of SERR. WebThe mechanical model of the W-DCB was built using elastic foundation theory to obtain expressions for the deflection and warping angle at the loading end and crack front, respectively. The results revealed that axial force F x modified the end correction term of W-DCB relative the compliance formula to the DCB. relaunche
