Span Load Distribution on Two Monoplanes Wing Models as Affected by Twist and Sweepback [PDF]

The results presented in this note show the effect of twist and sweepback on the span load distribution over two monoplane wing models. The tests were made in the Atmospheric Wind Tunnel of the Langley Memorial Aeronautical Laboratory. The data are taken

Shadow-free multimers as extreme-performance meta-atoms

, 2017
We generalize the concept of parity-time symmetric structures with the goal to create meta-atoms exhibiting extraordinary abilities to overcome the presumed limitations in the scattering of overall lossless particles, such as non-zero forward scattering ...

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

Advanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

A Structural Safety Analysis of Buildings During Construction [PDF]

, 1981
The safety of steel buildings, constructed by the tier method, is evaluated. The probability of failure of steel frames supported on temporary connections is examined during the different stages of completion.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Axial and Lateral Crushing of Elliptical Composite Tubes [PDF]

, 2003
Reduce structural weight, design flexibility, and improved structure safety, are the features offered by composite materials. Composite materials provide higher or equivalent crash resistance as compared with their metallic counterparts and therefore ...

Investigation of Thermo‐Chemical Processes in Commercial MgO‐C Refractory Bricks With and Without MgO‐C Recyclate at Elevated Temperatures

Advanced Engineering Materials, EarlyView.
This study investigates thermo‐chemical processes during high‐temperature testing of two commercial MgO‐C brick grades, one containing 47.5 wt.% MgO‐C recyclate. Using ETV, DTA/TG‐MS, XRD, and SEM/EDS/EBSD, mechanisms such as carbothermal reduction of magnesia, impurity incorporation into the secondary MgO surface layer, and calcium‐rich phase ...

Quantitative Nanofriction Characterization of Corrugated Surfaces by Atomic Force Microscopy

, 2003
Atomic Force Microscopy (AFM) is a suitable tool to perform tribological characterization of materials down to the nanometer scale. An important aspect in nanofriction measurements of corrugated samples is the local tilt of the surface, which affects the

Evaluating Energy Absorption Performance of Filled Lattice Structures

Advanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

INFLUENCE OF SOIL STRENGTH PARAMETERS ON THE LATERAL PILE RESPONSE

Diyala Journal of Engineering Sciences, 2010
A three-dimensional finite element technique has been used to analyze the single pile lateral under pure lateral load. The main objective of this study is to assess the influence of soil strength parameters (c, ) on the lateral behavior of single pile.
