Effect of Layer Orientation on Mechanical Properties of Rapid Prototyped Samples
TLDR
In this article, tensile strength, modulus of rupture, and impact resistance were found for different layer orientations of ABS rapid prototype solid models, fabricated by a Stratasys rapid prototyping machine.Abstract:
Tensile strength, modulus of rupture, and impact resistance were found for different layer orientations of ABS rapid prototype solid models. The samples were fabricated by a Stratasys rapid prototyping machine in five different layer orientations. The 0° orientation where layers were deposited along the length of the samples displayed superior strength and impact resistance over all the other orientations. The anisotropic properties were probably caused by weak interlayer bonding and interlayer porosity.read more

Influence of Layer Thickness and Raster Angle on the Mechanical Properties of 3D-Printed PEEK and a Comparative Mechanical Study between PEEK and ABS
TL;DR: A comparison was made between the mechanical properties of 3D-printed polyether-ether-ketone (PEEK) and acrylonitrile butadiene styrene (ABS) parts and the results indicate that the mechanical Properties of 2D- Printed PEEK are superior to 3 D-printed ABS.

Mixed mode cracking in layered materials
John W. Hutchinson,Zhigang Suo +1 more
TL;DR: In this article, the authors describe the mixed mode cracking in layered materials and elaborates some of the basic results on the characterization of crack tip fields and on the specification of interface toughness, showing that cracks in brittle, isotropic, homogeneous materials propagate such that pure mode I conditions are maintained at the crack tip.

Strain energy release rate analysis of delamination in a tapered laminate subjected to tension load
TL;DR: In this paper, a tapered composite laminate subjected to tension load was analyzed using the finite element method, where the delamination was assumed to initiate at the thin end of the taper on a -45/-45 interface and was simulated in both directions.
