Thermoplastic composites offer many opportunities for aeronautics. Among them is the possibility of overmolding composite parts to obtain finished “netshape” in medium series. This paper presents complexity manufacturing method and defects that may occur some grid-stiffened overmolded using aeronautic thermoplastics. The results impact tests up 15 J carried out at various locations plates grid ...

The damage tolerance behavior of integrally and conventional stiffened panel is investigated based on the fracture mechanics and finite element analysis. The load bearing capability and crack growth characteristic of both types of the stiffened panels having same configuration subjected to distributed tensile load is examined in this paper. A fourteen-stringer stiffened panel is analyzed for a ...

Structures that have components require particularly strong strengthening without the use of large amounts material grid stiffened structures, modified for purposes single application structure is utilised in. Modern structures evolved and deployed advanced materials, designs manufacturing techniques. Due to additive boom in industries, any such manufactured with metals significantly cheaper wh...

An analytical investigation is conducted to predict the post-buckling strength of laminated composite stiffened panels under compressive loads. When a stiffened composite panel buckles, the skin would deform into a sinusoidal mode shape, and hence induces additional moments and forces near the skin-stiffener interface region. These induced loads would cause the existing small edge delamination ...

The use of composite laminate materials has increased rapidly in recent years due to their excellent strength to weight ratio and resistance to corrosion. In the construction of marine vessels, stiffened plates are the most commonly used structural elements, forming the deck, bottom hull, side shells and bulkheads. This paper presents the use of a stochastic approach to the design of stiffened ...
