The Gap Test: Effects of Crack Parallel Compression on Fracture in Carbon Fiber Composites
Jeremy Brockmann, Marco Salviato
This paper explores the global Mode I fracture energy of a carbon fiber composite subject to a biaxial stress state at a crack tip, specifically in which one stress component is co…
Stress Distributions and Notch Stress Intensity Factors in Multimaterial V-notches Under Antiplane Shear and Torsion
Marco Salviato
This study investigates how the insertion of multimaterial circular regions embracing the tip of a finite V-notch can be used to reduce the Notch Stress Intensity Factors (NSIFs) i…
Effects of Out Time on the Mechanical and Fracture Properties of Chopped Fiber Composites Made From Repurposed Aerospace Prepreg Scrap and Waste
Troy Nakagawa, Seunghyun Ko, Cory Slaughter +3
In this study, the effects of prepreg out time on the mechanical and fracture properties of Discontinuous Fiber Composites (DFCs) are investigated. Carbon fiber prepregs are aged a…

Direct Testing of Gradual PostPeak Softening of Notched Specimens of Fiber Composites Stabilized by Enhanced Stiffness and Mass
Zdenek P. Bazant, Viet T. Chau, Gianluca Cusatis +1
Static and dynamic analysis of the fracture tests of fiber composites in hydraulically servo-controlled testing machines currently in use shows that their grips are much too soft a…
Experimental and Numerical Investigation of Intra-Laminar Energy Dissipation and Size Effect in Two-Dimensional Textile Composites
Marco Salviato, Kedar Kirane, Shiva Esna Ashari +2
Design of large composite structures requires understanding the scaling of their mechanical properties, an aspect often overlooked in the literature on composites. This contributio…
Spectral Stiffness Microplane Model for Quasibrittle Textile Composites
Marco Salviato, Shiva Esna Ashari Esfahani, Gianluca Cusatis
The present contribution proposes a general constitutive model to simulate the orthotropic stiffness, pre-peak nonlinearity, failure envelopes, and the post-peak softening and frac…
Modeling of Polymer Clay Nanocomposite for a Multiscale Approach
Paul E Spencer, John Sweeney
The mechanical property enhancement of polymer reinforced with nano-thin clay platelets (of high aspect ratio) is associated with a high polymer-filler interfacial area per unit vo…
