Abstract
This study presents an analytical model of low-velocity impact on composite plates, possessing either flat or cylindrical shapes. The overall plate`s stiffness properties are varied with an additionally assembled Ω-stringer and embedded shape memory alloy wires in the composite material, using only the shape memory effect. This analytical approach enables a low-effort but sufficiently accurate design of low-energy-impacted structures. Comprehensive analytical equations are developed based on the inclusion of the stringer effect on the curved panels. For both stringer-stiffened and non-stiffened plate models, parameter variations regarding the impact and shape memory alloy (SMA) wire integration are conducted. The effects can be classified as changes in essential and acquired stiffness. Our results indicate that SMAs improve the energy absorption capability of stiffened composite panels.
期刊介绍:
Applied Composite Materials is an international journal dedicated to the publication of original full-length papers, review articles and short communications of the highest quality that advance the development and application of engineering composite materials. Its articles identify problems that limit the performance and reliability of the composite material and composite part; and propose solutions that lead to innovation in design and the successful exploitation and commercialization of composite materials across the widest spectrum of engineering uses. The main focus is on the quantitative descriptions of material systems and processing routes.
Coverage includes management of time-dependent changes in microscopic and macroscopic structure and its exploitation from the material''s conception through to its eventual obsolescence.
