The microstructure, deformation, and fracture behavior of commercial ABS resins were investigated. Fracture mechanics studies were carried out under both static and dynamic conditions.
A Study of the Deformation and Fracture of a Dual-Phase A metallographic study of the tensile deformation and fracture of a commercial dual-phase steel shows that extensive plastic deformation of the martensite The average load-transfer stress in martensite was roughly calculated from a shear-lag model, and it was found that it exceeds the estimated martensite yield stress value at strains corresponding to the ultimate uniform elongation, and beyond.
Mar 01, 1986 · EXPERIMENTAL The deformation and fracture behavior in two different purities of Ni, each having varying carbon contents, were investigated. One material was a rela- tively pure Ni which had a total substitutional im- purity content of <400 at.ppm (this being the max- imum total level detected in any sample by spark-source mass spectrometry) with the main im- purity being Si (50-100 at.ppm).
An experimental investigation of deformation and fracture Large inelastic deformations were observed in hydrated condition, which were explained by sliding of the tablets on one another and progressive locking generated by their microscopic waviness. Fracture experiments were also performed, and for the first time the full

Deformation and Fracture of Solid-State Materials Results of the numerical study indicate that development of stress concentration plays a key role in the transition from advanced deformation to fracture, which is accompanied by the change of
Dynamic ESPI Evaluation of Deformation and Fracture Mar 20, 2021 · The deformation and fracture mechanism in 7075 aluminum alloy is discussed based on a field theoretical approach. A pair of peak-aged and overaged plate specimens are prepared under the respective precipitation conditions, and their plastic deformation behaviors are visualized with two-dimensional electronic speckle pattern interferometry (ESPI).

In situ studies and modeling of the deformation and In situ deformation and fracture studies were performed on wrought Zircaloy-4 and Zircaloy-2 to evaluate the mechanism for fracture initiation and propagation over a range of stress-state defined as triaxiality. High values of triaxiality () were achieved using the pre-cracked CT specimen ( 1.7), intermediate values ( = 0.8-1.2) were produced for a symmetric notched specimen, lower
Mechanisms of Deformation and Fracture ScienceDirectThe papers explore the mechanisms underlying deformation and fracture of materials such as pearlite, metals, quartz, soils, and rocks. Results of theoretical and experimental studies on topics ranging from electromagnetic detection of low-cycle fatigue to stress and strain distribution in
As stress and strain increase, rocks first experience elastic deformation (and can return to their original shape) until the elastic limit is reached, depicted at point X. After this point, rocks will fracture or experience plastic deformation, so that their original shape is destroyed Author:Randa Harris Source:Original Work License:CC BY

Numerical investigation of casing shear deformation ral fractures.24 Based on the interpretation of seismic data, natural fractures develop around the horizontal well while some horizontal wells even cross natural fractures. The cas-ing deformation points highly coincide with natural fractures/ faults, as shown in Figure 2. As per statistics, the deformation position is at a cer-
Fracture and deformation have long been areas of active study in mechanical engineering and materials physics. Yet, despite centuries of effort,unanswered fundamental questions continue to prevent accurate detailed predictions of how materials crack and bend.Study of the deformation characteristics and fracture Oct 01, 2018 · At present, most studies only focus on the study of fracture toughness under uniaxial conditions, whereas there are few studies on fracture toughness under triaxial conditions. In geotechnical engineering fields, rock is always in a triaxial state and is often subjected to confining pressure and axial pressure.
