Micro failure analysis of adhesively bonded joints enhanced with natural cork particles: Impact of overlap length and particles volume fraction

Alireza Akhavan-Safar, Ana Queirós Barbosa, Lucas Filipe Martins da Silva, Majid Reza Ayatollahi

In this work, the effects of natural particles on the micro failure mechanisms and static strength of an epoxy are studied using scanning electron microscope (SEM) technique. To this end, bulk specimens and adhesively bonded single lap…

Stress Intensity Factor Equations for the Evolution of Surface and Corner Cracks to Through Cracks

Antonio Miranda, Rafael Marques, Marco Antonio Meggiolaro, Jaime Tupiassú Pinho de Castro

Part-through surface or corner 2D cracks are commonly found in structural components, even because practically all fatigue cracks tend to start this way. It is a reasonable hypothesis to model them assuming the shape of their fronts is…
