Fracture toughness, critical strain energy release rate, and stress intensity factor were determined for experimental commercial restorative resins. A composite resin had lower resistance to arack initiation than an unfilled acrylic resin. The data consistent with surface failure observed in single-pass wear studies of these
This paper presents a critical review of analytic solutions for bending and buckling flat, rectangular, orthotropic thin plates. Considered are plates with all edges simply supported, two supported clamped, clamped. An orthotropy resealing technique is employed to simplify the analysis. The material characterized by non-dimensional parameters, λ = (D22/D11 η (D12 + 2D26)/√D11D22. When ≈ 1, many can be obtained directly from corresponding isotropic results. Systematic comparisons finite...
The mode of surface failure commercial and experimental restorative resins composites was evaluated with a single-pass sliding test. wear is determined by the resistance material to penetration deformation during sliding.
Decisions about sensor placement in cities are inherently complex, balancing social-technical, digital, and structural inequalities with the differential needs of populations, local stakeholder priorities, technical specificities sensors themselves. Rapid developments urban data collection geographic science have potential to support these decision-making processes. Focusing on a case study air-quality Newcastle-upon-Tyne, UK, we employ spatial optimization algorithms as descriptive tool...
In order to replicate the fracture behavior of intact human skull under impact it becomes necessary develop a material having mechanical properties cranial bone. The most important in surrogate were found be toughness and tensile strength tables as well bending three-layer (inner table-diplöe-outer table) architecture skull. materials selected represent consisted two different epoxy resins systems with random milled glass fiber enhance stiffness diplöe three low density foams. Forty-one...
Abstract The wear of dental amalgam was studied by single‐ and double‐pass sliding a silicon carbide abrasion test. A dispersed showed significantly better resistance to two‐body than the spherical amalgams tested. determined penetration ductile mode surface failure over load range studied. Differences in restorative resins composites are discussed.
Particle accelerators require very tight tolerances on the alignment and stability of their elements: magnets, accelerating cavities, vacuum chambers, etc. In this article we describe Hydrostatic Level Sensors (HLS) for low frequency measurements used in a variety facilities at Fermilab. We present design features sensors, outline technical parameters, test calibration procedures, discuss different regimes operation give few illustrative examples experimental data. Detail results ground...
Three-dimensional finite element analysis was used to predict thermal stress distribu tions in thick graphite/epoxy laminates. The laminates analyzed were [O n /90 ] s and [+45 /-45 . For the laminates, high in-plane tensile normal stresses predicted transverse (2-) directions both 0° 90 ° plies. High inter laminar (z- or 3-direction) exist 90° plies near center of two opposite free edges, with large compressive interlaminar along other edges. Stresses be low all corners. In direction also...
Solid unstiffened, sandwich and hat-stiffened rectangular orthotropic fiber reinforced plastic (FRP) plates were tested for buckling by in-plane compression stresses deflections under uniform out-of-plane pressure. The solid unstiffened 154 × 77 cm (1 w) (72 36 in), while the 102 (48 in). Balsa core was used in hat-stiffeners. two short edges of clamped, long simply supported. free, clamped. load, as well from tests, then compared to those finite element analysis (FEA) analytic solutions....
Previously we had developed an articulated human body model to simulate the kinematic response external loadings, using CFDRC’s CoBi implicit multi-body solver. The anatomy-based can accurately account for surface loadings and interactions with environment. A study is conducted calibrate joint properties (for instance, rotational damping) of by comparing its those obtained from PMHS test under moderate loading conditions. Additional adjustments in input parameters also include contact spring...
