Over the past two decades, aircraft crashworthiness has seen major developments, mainly with modern computing systems and commercial finite element (FE) codes. The structure material have been designed to absorb more kinetic energy ensure enough safety during a controlled crash condition. However, fuselage section an onboard auxiliary fuel tank requires special arrangements, since inclined stru...

AlSi10Mg inclined struts with angle of 45° were fabricated by selective laser melting (SLM) using different scanning speed and hatch spacing to gain insight into the evolution of the molten pool morphology, surface roughness, and dimensional accuracy. The results show that the average width and depth of the molten pool, the lower surface roughness and dimensional deviation decrease with the inc...

During the analysis of reinforced concrete structures, the infill wall is usually simplified as a diagonal inclined strut to facilitate finite element modeling calculations. However, the actual seismic damage and single frame-filled wall pushover experimental results show that when the earthquake shear force is huge, the top of the infill wall and the beam–column connections are usually, thus t...

We present a case of intramural duodenal haematoma caused by inferior vena caval (IVC) filter strut perforation requiring innovative open and endovascular retrieval. A 32-year-old woman presents in shock with dull epigastric pain and non-bilious vomiting. She had previously had an IVC filter for deep venous thrombosis and pulmonary embolism. Computed tomography demonstrated strut perforation in...

Micromechanical methods to predict the fracture behavior and estimate the fracture toughness of cellular solids and foams are presented in this paper. The microstructure of the foam is modeled using finite elements. The struts of foam are modeled using either structural elements such as beams or three-dimensional solid elements. A portion of the foam containing an edge crack is modeled. Displac...

Stent insertion for cerebral aneurysm has been studied using ideal and realistic aneurysms in recent years. Stent insertion aims at reducing the flow in an aneurysm. To minimize the average velocity in an aneurysm, we applied optimization to the strut position in a realistic aneurysm based on computational fluid dynamics. The result shows the effect on velocity reduction of strut placement in t...

OBJECTIVES To introduce the cutting and suture technique of the caudal L-strut for the management of caudal septal deviation and to evaluate its efficacy and surgical outcomes. DESIGN Retrospective study. SETTING Tertiary care rhinology clinic. PATIENTS Forty-five patients who underwent endonasal septoplasty using the cutting and suture technique of the caudal L-strut. INTERVENTIONS Aft...

BACKGROUND The objective of this paper was to describe a novel technique for improving the maintenance of nipple projection in primary nipple reconstruction by using acellular dermal matrix as a strut in one of three different configurations, according to the method of prior breast reconstruction. The struts were designed to best fill the different types of dead spaces in nipple reconstruction ...

Almost all species of modern birds are capable of flight; the mechanical competency of their wings and the rigidity of their skeletal system evolved to enable this outstanding feat. One of the most interesting examples of structural adaptation in birds is the internal structure of their wing bones. In flying birds, bones need to be sufficiently strong and stiff to withstand forces during takeof...

AIM Our aim was to evaluate the safety and efficacy of the novel crescent-shaped PMMA strut for anterior spinal reconstruction and fusion in patients with thoracolumbar bust fractures. The surgical results using this technique are reviewed. MATERIAL AND METHODS Six patients suffering thoracolumbar and lumbar fracture using a crescent-shaped PMMA strut combined with fixation for reconstruction...
