This study aims to assess the delamination effect and predict evolution of damage in 3D printed specimens investigate mechanical behavior occurring due layers thermoplastic polymers. Thus, additively manufactured ABS samples are subjected tensile tests Made for different thicknesses by subtracting layer layer. The adherence between studied this paper. deposition is modeled as a laminated materi...

Delamination fracture of a two-dimensional functionally graded multilayered four-point bending beam that exhibits non-linear behaviour of the material is analyzed. The fracture is studied analytically in terms of the strain energy release rate. The beam under consideration has an arbitrary number of layers. Each layer has individual thickness and material properties. A delamination crack is loc...

An analysis of delamination for a thin elastic film, attached to a substrate a corner, is carried out. The film is in compression and the analysis is performed by combining results from fracture mechanics and the theory of thin shells. The results show a very strong dependency of the angle of the corner. In contrast with earlier results for delamination on a flat substrate, the present problem ...

The distinguishing characteristics of carbon fibre reinforced laminates, like low weight, high strength or stiffness, had resulted in the increase of their use during the last decades. Although parts are normally produced to “near-net” shape, machining operations like drilling are still needed. In result of composites non-homogeneity, this operation can lead to delamination, considered the most...

Understanding what happens in terms of delamination during buckling of laminate materials is of importance across a range of engineering sectors. Normally concern is that the strength of the material is not significantly impaired. Carton-board is a material with a laminate structure and, in the initial creation of carton nets, the board is creased in order to weaken the structure. This means th...
