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 ...

Accession Number: 83N22328; Document ID: 19830014057; Report Number: NAS 1.26:3682, NASA-CR-3682
Mathematical modeling of damage in unidirectional composites
Author(s): Goree, J. 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 ...

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 ...

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 ...

Analysis of a unidirectional, symmetric buffer strip laminate with damage
Author(s): Dharani, L. 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 ...

Analysis of a hybrid, uni-directional laminate with damage
Author(s): Goree, J. G.; Dharani, L. R.
Abstract: The fracture behavior of hybrid (buffer strip) laminated composites is predicted by a novel method in terms of material properties, geometry, and internal damage. Attention is given to the cases of broken fibers in a ...
