MULTISCALE MODELING OF VISCOELASTIC BEHAVIOR OF UNIDIRECTIONAL COMPOSITE LAMINATES AND DEPLOYABLE STRUCTURES

Due to the inherent viscoelasticity of constituent matrix and the possibility of long-term storage, space deployable structures made of composites are likely to exhibit relaxation in the stored strain energy, which may degrade their deployment performance.This paper presents a bottom-up finite element based multiscale computational strategy that br

Results of creep tests of two Fe-27 at.% Al-based alloys with additions of 2.7 and 4.8 at.% of niobium conducted in the temperature range from 650 °C to 900 °C in the authors’ laboratory are presented.The purpose of the study is to supplement previous work on Fe-Al-Nb w insta saree alloys to obtain a more complete overview of creep
