DESCRIPTION:Prof. Tomonaga OKABE\nAssociate professor in Department of Aer
 ospace Engineering\,\nTohoku University\, Sendai\, Japan\nComposite materi
 als are gaining wide applications in aircraft\, spacecraft\, automotive an
 d energy generation. For example\, in the case of the Boeing 787 Dreamline
 r\, carbon fiber reinforced plastic composites are used for the main struc
 tural members. However\, their design and analysis still presents challeng
 es due to the multiple scales from micro-level to the structural. For exam
 ple\, for analyzing the deformation of a composite structure\, it should b
 e regarded as an anisotropic body at a macroscopic scale. However\, to ana
 lyze its failure or damage\, one must use microscopic analysis with the re
 presentative volume elements (RVEs) considering micro cracks in matrix and
 /or fiber/matrix interfaces. Furthermore\, for fabrication and processing 
 of composite structures\, the molecular scale at which fiber and resin rea
 ct also must be considered (i.e. atomistic modeling).\nThis presentation w
 ill introduce the numerical modeling of fiber reinforced plastic composite
 s considering bridging of scales. The studies presented in this presentati
 on are not always tightly connected in a scheme\, and each scale is indepe
 ndently modeled in many cases. However\, the results from a series of mode
 ls give us a concise view of how to connect those scales and to use the co
 mposite wisely.\nThis presentation discuss (1) Numerical simulation of int
 erlaminar damage propagation in CFRP cross-ply laminates under transverse 
 loading and impacts\, (2) Numerical method for failure simulation of unidi
 rectional fiber reinforced plastic composites\, (3) Micromechanics on the 
 rate-dependent fracture of discontinuous fiber reinforced plastic composit
 es\, (4) A periodic unit-cell simulation of transverse tensile failures in
  unidirectional carbon fiber reinforced composites (5) Effect of Nanostruc
 ture upon the Deformation Micromechanics of Carbon Fibres and (6) Atomisti
 c simulation of the curing reaction of Epoxy resin.
