| description | To understand how fractal parameters affect the dynamic properties of real-life structures
such as aircraft fuselages and building structures, an improved contact model of a joint interface is
proposed, and it includes the transition region demarcating the elastic and the plastic region.
Thereafter, detailed numerical analysis is conducted to obtain the revised contact load and the
contact stiffnesses equations. The stiffnesses consists of the normal and the tangential contact
stiffness. Relationships are then established to further understand the effect of applied contact
load to the 2 aforementioned contact stiffnesses. Numerical simulation using MATLAB is then
employed to analyse the corresponding effects of various parameters to the translational contact
stiffness based on the applied load. Then, Finite Element Analysis (FEA) software, ABAQUS, is
further conducted to explore how these various parameters affect the dynamic properties of the
contact model in natural frequency measured in 6 different modes of shapes. The contact model in
FEA is modelled as the hybrid model, in which the materials are the isotropic aluminium alloy
7075-T651 and the orthographic carbon/epoxy composite. |
