Crashworthiness capability of jute and glass fibre reinforced epoxy tubes under quasi-static loading condition for automotive application
During last few years, the interest in using natural fibers as reinforcement in polymers has increased dramatically. Natural fibers are not only strong and lightweight but also relatively very cheap. This study examined the potential utilization of jute in the crash energy absorption. A combination …

Adaptively prestressed concrete structures
… react effectively to only one dominant loading condition. Adaptive structures in contrast can deal with multiple loading conditions and unanticipated events at the same time. Truly adaptive civil structures do not exist. Concrete structures can be made adaptive through variable …

A photoelastic technique for the determination of stress intensity factors for Mode III loading
… of the stress intensity factors due to Mode III loadings from photoelastic data is developed. The results are supported by a series of stress freezing photoelastic experiments conducted on circumferentially notched round bars to which torsional loads were applied yielding a pure Mode III loading …

Two-Way Behavior and Fatigue Performance of 3-D GFRP Sandwich Panels
… mid span, and tested subjected to a quasi-static loading condition up to failure. The parameters under consideration for testing the two-way panels were also used in a one way configuration under two fatigue loading condition. The fatigue test consists of three point flexural loading configuration …

Denitrification of Recirculating Aquaculture System Waters Using an Upflow Biofilter and a Fermented Substrate
… nitrate wastewater supplied at two nitrate loadings, 1.13 and 2.52 kg NO3-N/m3/day. A supplemental carbon source was provided primarily through the fermentation of fish food which generated volatile fatty acids (VFA) in the form of acetic, propionic, isobutyric, n-butyric, 2-methylbutyric, …

Análise de estruturas reticuladas pelo método das matrizes de transferência
… linear elastic support. Besides the usual loading condition and uniform temperature change, they allow us to get the influence lines through imposed displacements at joints. This way, these programs are efficient enough in the analysis of archs, helicoidal beams and viaducts transformed in …

The role of dislocation activities in the brittle-ductile transition in silicon single crystals
… silicon single crystals, one must identify the conditions for dislocation nucleation at crack tips. In the present study, dislocation nucleation in $\{110\}$$$ oriented silicon is determined experimentally. The specimens are first statically loaded at high temperatures, and then fractured at …

Combined Tension-Torsion Loading of Braided Composite Structures
… braided composites under tension and torsion loading have been studied individually. Mechanical behaviour of braided composites under combined tension-torsion loading is common, yet no studies have explored this effect. In this study, mechanical properties of carbon fibre, fibreglass and …

Computational modeling of hydrogen embrittlement of iron aluminides
… ternary alloy (FA186) under constant tensile loading condition. This may due to the effect of smaller grain sizes caused by alloy addition. To further investigate the grain boundary size effect as related to the susceptibility of hydrogen embrittlement, comparative finite element modeling …

Biomechanical adaptations of human gait due to external loads
… relative phase as a metric to determine loading condition is quantified by intra-class correlation coefficients (ICC) and the number of required trials is computed. The ICC(2, 1) values showed moderate reliability and 3 trials are sufficient to determine lower body kinematics under two …

An Investigation and Comparison of Accepted Design Methodologies for the Analysis of Laterally Loaded Foundations
… to take the load imposed on it under the worst loading condition. Typically, pile length, pile section, soil type, and pile restraint dictate the analysis. This paper presents different methods, specifically Broms' method and the p-y method, for both the analysis and design of laterally loaded …

Effects of the alkali-silica reaction on unloaded, statically loaded and dynamically loaded reinforced concrete beams.
… beams were tested under the following loading regimes for the duration of the experiment: unloaded, statically loaded and dynamically loaded to unfactored service load. The experiment was conducted until an amount expansion had occurred in the reactive specimens. Three general aspects …

Failure strength and mechanism of composite laminates under multiaxial loading conditions
… (BCC(n)) were tested in a biaxial compression loading condition to study failure behavior of notched laminates under a biaxial stress state. Failure mechanisms of notched and unnotched composite laminates have been studied based on the test data and failure surface examination.

Microscale Investigation of the Influence of Interparticle Cohesion on the Macro-Behaviour of Soil
… the formation of angle of repose, shearing under loading condition and clogging behaviour when fluid is involved. Different levels of cohesion between particles are integrated in numerical models and the results are validated against well-known experimental and analytical methods. The results show …
