Sorted by: Date Added To NTRS in Descending order Mathematical modeling of damage in unidirectional composites Author(s): Goree, J. G.; Dharani, L. R.; Jones, W. F. Abstract: A review of some approximate analytical models for damaged, fiber reinforced composite materials is presented. Using the classical shear lag stress displacement assumption, solutions are presented for a unidirectional ... NASA Center: NASA (non Center Specific) Publication Year: 1981 Added to NTRS: 2005-10-13 Accession Number: 81N29166; Document ID: 19810020628; Report Number: NASA-CR-3453 Shear-lag analysis of a hybrid, unidirectional composite with fiber damage Author(s): Goree, J. G.; Dharani, L. R. Abstract: Development of a method of analysis capable of predicting accurately the fracture behavior of unidirectional hybrid (buffer strip) composite laminates was studied. Three particular solutions are discussed in detail: broken ...

G.; Dharani, L. R.; Jones, W. F. Abstract: Extending the work of Goree and Gross (1979), solutions are given for a two-dimensional region of unidirectional fibers embedded in an elastic matrix whose initial flaw may take the form of a transverse notch, a rectangular ... NASA Center: NASA (non Center Specific) Publication Year: 1983 Added to NTRS: 2004-11-03 Accession Number: 83A32344; Document ID: 19830051126 Non-steady state cracking in ceramic matrix composites Author(s): Dharani, L. R.; Chai, L. Abstract: A micromechanics analytical model based on the consistent shear lag theory is developed for predicting the failure modes in a fiber-reinforced unidirectional ceramic matrix composite. The model accounts for the relatively ... NASA Center: NASA (non Center Specific) Publication Year: 1989 Added to NTRS: 2004-11-03 Accession Number: 90A27083; Document ID: 19900040028 Analysis of a hybrid-undirectional buffer strip laminate Author(s): Dharani, L. R.; Goree, J. G. Abstract: A method of analysis capable of predicting accurately the fracture behavior of a unidirectional composite laminate containing symmetrically placed buffer strips is presented. As an example, for a damaged graphite/epoxy ...

R.; Goree, J. G. Abstract: A method for predicting the fracture behavior of hybrid buffer strip laminates is presented in which the classical shear-lag model is used to represent the shear stress distribution between adjacent fibers. The method is ...
