Investigation of crack growth along curved interfaces in L-shaped composite and polymers
Yavas, D.; Gozluklu, B.; Çöker, Demirkan (2014-01-01)
Delamination in unidirectional L-shaped composite laminates is modeled with two L-shaped polycarbonate plates bonded to each other where the effect of pre-crack length on the stability of the crack growth is investigated experimentally and computationally. In the experimental study, a unique testing fixture with a sliding platform is designed to create a pure vertical displacement to one of the arms. The full-field technique of photoelasticity is used in order to visualize isochromatic fringe pattern around...

Investigation of microstructure inhomogeneity in SiCp-reinforced aluminum matrix composites
Gacsi, Zoltan; Gür, Cemil Hakan; Makszimus, Andrea; Pieczonka, Tadeusz (2007-01-01)
The type, volume fraction, size, shape and arrangement of embedded particles influence the mechanical properties of the particle reinforced metal matrix composites. This presents the investigation of the SiC particle and porosity distributions in various aluminum matrix composites produced by cold- and hot-pressing. The inicrostructures were characterized by optical microscopy and stereological parameters. SiC and porosity volume fractions, and the anisotropy distribution function were measured to establish...

In this study slow heating response of small-scale test items and full-scale munitions due to thermal decomposition of explosives was investigated. Thermal decomposition parameters of the four most prevalent explosive formulations (from P1 to P4) used in defense industry were determined using non-isothermal thermogravimetric analysis and differential scanning calorimetry. Considering these parameters, an igniter formulation was developed to burn the explosive formulations in a predefined temperature before ...

The aim of this study is to find out the relations of stress triaxiality and Lode angle parameter with the deformation characteristics of deep drawing process. For this purpose, deep drawing process is analyzed numerically by using different yield criteria, ductile criteria and hardening models for two different sheet materials. The simulations are carried out by using the finite element method. Square and cylindrical cups made of Al-2024 aluminum and AISI 304 steel are formed. Von Mises and Hill48 yield cr...
