Bolted Joints in Laminated Composites

Expressions were presented which can be used to estimate the strengths of continuous fiber reinforced composite laminates containing pin-loaded holes. The expressions apply to laminates containing either a single pin loaded hole, a single row of pin loaded holes, or two parallel rows of pin loaded holes.

survey on the rule of the due & hindering relying on the sheikh ansaris ideas

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...

Hierarchical optimization of laminated fiber reinforced composites

1. Abstract The aim of this work is to perform hierarchical optimization [1] in laminated composite structures, considering simultaneously macroscopic and microscopic levels in the design of the structure and its material. In the macroscopic level, the optimization algorithm cares with orientations and fiber volume fractions of unidirectionally reinforced composite material layers. In the micro...

Mode I Failure of Laminated Polymeric Composites

A mechanical model for the prediction of mode I delamination failure of a laminated double cantilever beam (DCB) type specimen is presented. The volume of material ahead of the crack tip that experiences high stresses due to the presence of the crack tip was replaced by a nonlinear elastic spring foundation. The volume undergoing global deformation due to the external loading was replaced by a ...

Bulk Wave Characterization of Laminated Composites

Composite materials are currently seeing wider use in the aerospace and automobile industries. Composites offer many advantages over conventional materials, such as a greater strength to weight ratio and the ability to engineer their mechanical properties to a specific task. The major problems associated with composites are cost and reliability. Like virtually all engineering materials, composi...
