Experimental evaluation of the similarity in the interface fracture energy between PMMA/epoxy/PMMA and PMMA/epoxy joints

On different 3D printing methods and fracture performance in DCB composite specimens including structured interfaces

“…They allow us to benefit from the vast number and diversity of solutions that have been perfected over millions of years of evolution. Specifically, they arrest crack propagation and prevent catastrophic failure [1][2][3][4]. Although mimicking the properties of natural material is a complex process, the first steps in characterization, modeling, and manufacturing have been taken.…”
