Tensile behavior of unidirectional and cross-ply ceramic matrix composites
The tensile behavior of two ceramic matrix composites (CMC's) was observed. The materials of interest in this study were a glass-ceramic matrix composite (GCMC) reinforced with Nicalon fibers and a Blackglas™ composite also reinforced with Nicalon fibers. Both had a symmetric cross-ply layup. …

Tensile behavior of aluminum reinforced with angle-ply boron epoxy laminates
An experimental investigation of the tensile behavior of aluminum reinforced with angle-ply boron/epoxy laminates was conducted. It is shown that the ultimate stresses of a wide variety of laminate configurations fall within a very narrow range of values. Some configurations of composite reinforced …

Characterizing the tensile behavior of additively manufactured Ti-6Al-4V using multiscale digital image correlation
In this work, the tensile behavior of an additively manufactured (AM) alloy, titanium 6Al-4V, or Ti-6Al-4V (by wt. 90% titanium, 6% aluminum, 4% vanadium), is examined on multiple length scales using two-dimensional (2-D) digital image correlation (DIC) techniques. Ti-6Al-4V is one of the AM metals …

Micromechanisms of paperboard deformation
… were conducted to determine the stress-strain behavior and corresponding deformation mechanisms under several well-controlled loading conditions. These include through-thickness compression, shear, and tension, as well as combined tension/shear loading. In-plane tensile behavior was also …

Viscoelastic Models for Ligaments and Tendons
… derived within this framework can illustrate the tensile behavior, stress relaxation and creep by as suming that the collagen fibers are elastic and the surrounding proteoglycan-rich matrix is viscoelastic. The collagen fibers are represented by linear elastic springs that are engaged to support …

Fracture behavior of CPM 10V
… fatigue crack growth rate (da/dN), and tensile behavior of a commercial powder metal alloy, CPM 10V, was investigated. Fracture toughness was increased by increasing the tempering temperatures and decreased by increasing the austenitizing temperature. These changes were related to …

Crack coalescence in granite
… and coalescence patterns suggest a more tensile behavior as grain size increases from gypsum to marble to granite. Similar to previous work in marble and granite, white patches are observed during compression tests. These white patches can be categorized as either diffuse or linear, with …
