Laboratory evaluation of cracking in asphalt concrete
… notched asphalt concrete samples in three point bending. Load and crack width data at different locations of the sample were captured in real time using Linear Variable Differential Transformers (LVDTs). Crack initiation, path, and velocity are examined with varying notch tip location, mixture …

An investigation of space suit mobility with applications to EVA operations
… history. Two physics-based models describing the bending load-deflection characteristics of pressurized fabric cylinders were compared to the experimental space suit data. The beam model assumes that bending deflections are completely attributable to elongation of the fabric cylinder wall, while …

Design and Performance of Cold Bent Glass
… challenge by developing cold bent glass. Cold bending involves the straining of relatively thin glass components, at ambient temperatures, and is a low energy and cost effective manner of creating curvilinear forms. However, cold bending is not yet widely established as a reliable method. The …

Biomechanical evaluation of two methods of surgical stabilization of the atlantoaxial joint
… these two techniques in ventral-to-dorsal bending in both mature and immature dogs. Seventeen normal canine cadavers <15kg were collected and radiographed to determine skeletal maturity. The cervical spines were dissected leaving bony and ligamentous structures intact. Eight mature spines …

Multidisciplinary Design Optimization and Industry Review of a 2010 Strut-Braced Wing Transonic Transport
… strut-braced wing, which uses a strut for wing bending load alleviation, allowing increased aspect ratio and reduced wing thickness to increase the lift to drag ratio. The thinner wing has less transonic wave drag, permitting the wing to unsweep for increased areas of natural laminar flow and …

A study of the behaviour of pressurized piping elbows
The behaviour of piping elbows under bending and internal pressure is more complicated than expected. The main problem is that the coupling of bending and internal pressure is non-linear; stress and displacement cannot be added according to the principle of superposition. In addition, internal …

Active pitch control of an oscillating foil with biologically-inspired boundary layer feedback
… wing motion in response to the flow-induced bending load experienced by sensory hairs mounted on the wing. Such hairs have been observed on bats, and biological studies suggest that an associated feedback controller may play an important role in enabling bats' well-known mastery of light. The …

Finite element analysis of composite tubes with integral ends subjected to bending loads
… was performed to study the effect of applied bending loads on laminated composite tubes. Elasticity-based linear models were developed using finite element software to predict stresses within the individual plies of the tubes. The tubes under investigation were graphite/epoxy laminated …

Effects of kenaf/polyester blending ratios on physical and mechanical properties of yarns produced from ring spinning system
… of the yarns. This produced fibers with a higher bending load capacity. It was also noted that the kenaf/polyester hybrid (50% kenaf and 50% polyester) had improved physical and mechanical properties. Nonetheless, the subsequent increment in kenaf composition did not improve the strength of the …

The Relationship Between the Osteonal Cement Line and Bone Strength
… a material. In Part 7, tibiae were mechanically loaded, and slices subsequently processed for image processing which quantified cement line length/unit area. The results indicate that the average load necessary to completely fracture female tibiae (4.17 kN) was significantly less (p<0.05) than …

Numerical simulation of damage and progressive failures in composite laminates using the layerwise plate theory
… laminate with free edges subjected to tensile loading is studied. The ultimate stresses and strains predicted by the Generalized Layerwise Plate Theory (GLPT) and the more widely used First Order Shear Deformation Theory (FSDT) are compared with experimental results. The predictions of the GLPT …

MULTI-SCALE MECHANICS OF COMPOSITE SANDWICH STRUCTURES WITH BIOLOGICALLY INSPIRED FIBER REINFORCED FOAM CORES: A POTENTIAL TEMPLATE FOR DEVELOPING MULTIFUNCTIONAL STRUCTURES
… while the porous cellulose matrix controls load transfer and failure between macrofibers. Shear dominated debonding and pore collapse mechanisms have been identified as the leading modes of failure mechanism. The role of macrofiber volume fraction and strain rate on macroscale response and …

Charge-sensitive methods for the off-design performance characterization of organic Rankine cycle (ORC) power systems
… fluid charge distribution is measured on-line by bending load cells and infrared imaging techniques. Following a complete experimental campaign (which includes more than 300 steady-state points), a dual reconciliation method is applied on the raw measurements to obtain a reference dataset. An …

Entwicklung eines Berechnungsmodells für das Langzeitverhalten von Stahlbeton und textilbewehrtem Beton bei überwiegender Biegebeanspruchung
Tragwerke aus Stahlbeton weisen infolge des Kriechens und Schwindens des Betons ein zeitveränderliches Materialverhalten auf. Die Folge sind Umlagerungen der im Querschnittsinneren wirkende Kräfte und im Zeitverlauf zunehmende Verformungen. Zur Beurteilung dieses Langzeitverhaltens sind geeignete …
