Approximate Interlaminar Fracture Envelopes for Unidirectional E-glass/polyester Composite
(Budapest University of Technology and Economics, 2005)
In this paper an experimental study is performed in order to determine an approximate interlaminarfracture envelope of a unidirectional E-glass polyester composite. First, the pure mode-I fracturetoughness is determined ...
Application of prestressed composite beams in fracture mechanics
(Budapest University of Technology and Economics, 2007)
This work presents the mixed-mode I/II/III version of the prestressed end-notched flexure system for the general delamination characterization of composite materials. The novel fracture mechanical configuration combines ...
Analysis of the Interlaminar Crack Initiation in Mixed-mode I+II Composite Fracture Specimens
(Budapest University of Technology and Economics, 2003)
The interlaminar crack initiation in mixed-mode specimens was investigated through two- and three-dimensional finite element models. Elastic analysis was conducted to understand the crack initiation in glass-fibre/vinylester ...
Comparison of some Data Reduction Schemes for Composite Delamination Specimens
(Budapest University of Technology and Economics, 2004)
Three different solutions for orthotropic, beam-like fracture specimens were compared in the currentwork. A beam theory-based approach was developed previously by the author. Another solutionbased on refined plate theory ...
