This report presents a formal approach for optimizing the shape of freely supported isotropic plates to withstand air blast loading. Unique difficulties are presented by the nature of shortduration dynamic loading, viz. transient dynamic response, monitoring of maximum plastic strain failure at every point in the panel over time, optimizers that can handle non-differentiable, nonconvex and comp...
BACKGROUND Open reduction and internal fixation of proximal humerus fractures can be difficult to achieve adequate, complication free results due to osteopenia of the proximal humerus and unstable fracture patterns. This study aimed to compare the biomechanical properties of a novel hybrid fixed angle blade plate (Fx plate) with an established fixed angle locking plate (PHILOS plate). METHODS...
The paper analyzes the vertical penetration of a small object through a floating sea ice plate. The analysis takes into account the fact that the bending cracks reach only through part of the ice plate thickness and have a variable depth profile. The cracks are modeled according to the Rice-Levy nonlinear softening line spring model. The plate-crack interaction is characterized in terms of the ...
In the standard three-rail shear test, as described in “ASTM D 4255/D 4255M The standard test method for in-plane shear properties of polymer matrix composite materials by the rail shear method” the specimen is clamped with bolts. This however, requires drilling holes through the specimen, which of course is not ideal for composite materials, because of the occurring damage around the holes. Fu...
CFRP is an alternative technique for cracking control of high-chloride reinforced concrete (RC) beams. This research, therefore, investigates the strength performance and failure mode behaviour RC beams incorporated with sea sand bonded externally carbon fibre polymer (CFRP) plate. Sea used as a 100% replacement fine aggregate. Three batches were carried out in this including beam (no neither C...
Ferrocement as a form of reinforced concrete constructed of hydraulic cement mortar strengthened with closely spaced layers of continuous and relatively small diameter wire mesh. It has been used worldwide as a construction material to provide better construction and rehabilitation of structures. Moreover, there may be structural deterioration of ferrocement due to the exposure of saline water....
This paper presents experimental and numerical results for fully-clamped square steel plates to elucidate how the deformation failure are affected by presence of pre-formed holes, holes’ geometry, under confined blast loading. The geometry holes will be shown play a crucial role in plate. Numerical simulations successfully predict inelastic crack propagation observed experiments; and, it that v...
PURPOSE The purpose of this study was to compare the mechanical stability of three types of plate systems for opening wedge high tibial osteotomy. MATERIALS AND METHODS Forty-eight fresh frozen porcine tibia specimens were assigned to three different fixation device groups: Aescular group (16 specimens) was fixed with Aescular plates; Puddu group (16 specimens) with a Puddu plate, and TomoFix...
For prevention of soil compaction, knowledge of allowable compression stress limit (compaction strength) in soil is important. Pre-compaction stress ( σpc) was introduced as soil compaction strength and often used as a criterion for evaluation of soil susceptibility to compaction. In this research, pre-compaction stress was measured for a sandy loam soil with plate sinkage (PST) and confined co...
BACKGROUND Children need physical activity and generally do this through the aspect of play. Active play in the form of organized sports can appear to be a concern for parents. Clinicians should have a general physiological background on the effects of exercise on developing epiphyseal growth plates of bone. The purpose of this review is to present an overview of the effects of physical activit...
