The Effects of Strain Induced Softening on the Load Carrying Capability of Components
… bainitic microstructure with improved short term strength characteristics over the more commonly used annealed form. The bainitic material cyclically softens, however, losing as much as 30 percent of its initial strength in a few hundred cycles at post yield strain ranges. In most practical …

Durabilidade e módulo de elasticidade de misturas areia - cal - cinza volante
… of durability, elastic modulus, split tensile strength and unconfined axial compression strength of a sandy soil stabilized with lime and fly ash, and also, with the cement addition and replacing part of sand with crushed stone. The selected soil was a coastal dune sand, cohesionless and with …

An elastic-plastic interface constitutive model for combined normal and shear loading : application to adhesively bonded joints
… jump angle is found to drive the behavior of the initial strength values, as well as the critical and failure displacement jumps of the separate mechanisms that are used to define the model. A set of calibration experiments are performed to fully define an aluminum/adhesive/aluminum system …

THE EFFECTS OF INITIAL HIP ABDUCTION AND EXTERNAL ROTATION STRENGTH AND NEUROMUSCULAR FATIGUE OF THE GLUTEUS MEDIUS ON THE STAR EXCURSION BALANCE TEST IN MALE AND FEMALE HEALTHY SUBJECTS
… The objective of this study was to determine if initial hip muscular strength and gender affect neuromuscular performance on the Star Excursion Balance Test (SEBT) following fatigue of the hip musculature. In a randomized control trial, set in a laboratory, 20 male and 20 female recreationally …

Improving fatigue life predictions: theory and experiment on unidirectional and crossply polymer matrix composites
… response of the critical element. The residual strength of the critical element may then be continuously evaluated to predict failure. The statistical nature of material strength is accounted for by forcing the critical element SN Curve to yield a specimen initial strength distribution in …

Sustainable bacteria-based self-healing fiber reinforced concrete
… to measure compressive, tensile, and flexural strengths. In addition, SEM and EDS analyses for cracked and uncracked specimens were performed. The results showed a significant increase in the long-term compressive, tensile, and flexural strengths at 180 days by 47 percent, 80 percent, and 50 …

Silane Surface Modification of Boron Carbide in Epoxy Composites
… between BC and resin led to limited mechanical strength and durability. Hence, silane surface modification of BC particles was conducted with γ–glycidoxypropyltrimethoxysilane (GPS) as an aqueous solution to attain an 80%wt BC-epoxy PMC with improved strength and durability. Surface analysis on …

The isokinetic assessment of muscle strength in rugby union players.
Strength is an important requirement in the game of rugby union. Activities such as tackling, scrummaging, rucking, mauling make upper body strength essential for success at the higher levels of competition. This aspect of strength has been assessed by a variety of weight lifting tests but no tests …

Microangiographic comparison of the effects of the three-loop pulley and six strand Savage tenorrhaphy techniques on the equine superficial digital flexor tendon
… strain on the tenorrhaphy site that exceeds the strength of the repair itself. Extrapolation of complex, stronger tenorrhaphy patterns from human literature and applying them to equine patients has been challenging. Human tenorrhaphy techniques initially focused on strong repairs, which are able …

Theory protection in human associative learning and formally representing uncertainty about novel stimuli
… (reported in Chapter 2), human participants were initially trained with a set of cues, each of which was followed by the presence or absence of an outcome. In a subsequent training stage, two of these cues were trained together, and the amount learned about each of the cues was compared, using a …

Inverse Boundary Element/genetic Algorithm Method For Reconstruction O
… or along cooling hole centerline with a given initial strength distribution. The inverse problem iteratively alters the strength distribution of the singularities (sinks) until the measuring surfaces heat fluxes are matched. The heat flux distributions are determined in a post-processing stage …
