Development of experimental concepts for investigating the strength behavior of fine-grained cohesive soil in the Spacelab/space shuttle zero-g environment [PDF]
Three different sets of tests are proposed for the NASA Spacelab experimental program. The first of tests, designed to measure the true cohesion of several different soils, would be carried out in space through use of a specially prepared direct shear ...

The bias-extension test for the analysis of in-plane shear properties of textile composite reinforcements and prepregs: a review [PDF]
, 2016 The bias-extension test is a rather simple experiment aiming to determine in-plane shear properties of textile composite reinforcements. However the mechanics during the test involves fibrous material at large shear strains and large rotations of the ...

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

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 ...

MODELING THE DIRECT TENSILE STRENGTH FOR LIGNITE EXTRACTED AT U.M.C. PESTEANA USING THE FINITE-DISCRETE ELEMENT METHOD (FDEM) [PDF]
Fiabilitate şi DurabilitateIn rock mechanics labs, the tensile strength test is carried out by either direct or indirect methods. Among indirect test methods, the most common is a diametrical compression on a disk specimen, also known as the Brazilian Tensile Strength (BTS) test.

MECHANISM AND ESTIMATION OF TENSILE-REINFORCING EFFECTS IN THE DIRECT SHEAR TEST
Jioshinsetikkusu Rombunshu (Geosynthetics Engineering Journal), 2008 土の一様なひずみに起因する補強材引張力は常に補強材面に沿った摩擦力が作用するが，不連続な変位に起因する補強材引張力は摩擦力だけでなく補強材面に垂直な力が土に作用する．直接せん断(DS)試験では土のひずみよりも不連続な変位に起因する引張り補強効果が強度発現の主因となるため，土の摩擦力との釣合いを基本とするせん断強度の推定式では試験結果をうまく説明できない．そこで，本研究では，不連続な変位場で表れる力の釣合いをモデル化したせん断強度の推定式を提案し，補強土のDS 試験結果と比較した．その結果，提案式では引張力の発達分布の違いによる補強効果の差を表現でき，せん断強度を適切に評価できることがわかった．
