Ang, Soon Lim (2006) Predicting the crushing stress of composite materials. [USQ Project] (Unpublished)
A simple mathematical model for predicting the crushing stress of the composite
materials is presented in this report. The present knowledge of fracture mechanics
and strength of materials are used as a basis for the modeling process.
The fracture mechanics part of analysis was based on the energy release rate
approach. The energy release rate (G) of the proposed model was determined by
this approach. This energy release rate was based on the Mode 1 (opening or
tensile mode) failure. As for the strength of materials part of analysis, buckling
theory was used to determine the critical load of the fibre beams.
These two engineering concepts were combined to form the equation for the
proposed model. The derived equation should be a function of the materials
properties, geometric and physical parameters of the composite materials.
The calculated stresses from the derived equation were compared with
experimental data from technical and research papers. Good agreements shown in
the results are encouraging and recommendations for future analysis with
different modes of failure were also presented.
