... modulus of micro-machined samples are surprisingly lower, while failure strain is highest among line filling printed samples. Damage resistance was quantified in terms of work of fracture, and hexagonal filling provided better damage resistance than line filling patterns for conditions of 0 deg raster...

...Vishwas Divse; Suhas S. Joshi; Deepak Marla This work presents a 3D progressive damage model based on Puck’s failure theory and linear damage evolution in fiber-reinforced plastic (FRP) laminates. It includes shear nonlinearity, in situ strengths, equivalent stress–strain, and mixed-mode fracture...

The preheated sample fractured at the base metal, revealing a ductile fracture mode. A jig is designed and developed for this study...

The factors affecting the formation of adiabatic shear bands are explored based on the numerical simulation, which suggests that the magnitude of the temperature gradient...

For a random fiber orientation case, deformation of the unnotched specimen occurs by long-range fiber chains connecting the load inducing boundaries, and failure is by tearing the cross section.
