Non-destructive methods for testing material properties allow for multiple tests to be performed on the same sample, which will speed up the design and testing process for hydrogel contact lenses.
The aim of this work was to develop an advanced finite element model of a plate mill, including the major mill components, the mill set-up engineering condition, the profile of the mill rolls (incorporating ground-on profile, thermal camber and wear effects), the stock geometry and the stock material properties, allowing detailed study and simulation of plan-view shape evolution.
In some cases like HMX, the specific material properties allow techniques such as second harmonic generation to be used.
These increases in the bulk materials properties allow the nanocomposite hydrogel to withstand more forces during the lap shear adhesion testing.
It allows use of different grid sizes in different regions depending on the material properties and allows a relatively uniform grid spacing in the polar coordinate case.
As such, a procedure is outlined in this paper that applies a number of commonly accepted composite mechanics and shock physics theories in conjunction with generalised material properties which allows for the theoretical derivation of a complete material data set for utilisation of the new modelling capabilities.
Control of electromechanical properties allows for materials to be tailored for specific applications.
Measurements were complemented with calculations based on experimentally determined material properties, which allowed for separation of quenching and thermal stress contributions to final residual stress.
The effects of stress and temperature are incorporated in the elastic and time-dependent material properties, which allow prediction of time-dependent responses under general stress and temperature histories.
The former (softening representation), usually adopted in literature, consists of modelling LVI damages by lowering the elastic material properties which allowed investigating the Lamb wave propagation at different stages of LVI damages evolution.
