\title{Sorting Criterion for Slip and Twin system in HCP}


\author{YunJo Ro}

\maketitle
This document attempts to show how we sort the order of the slip and
twin system for Hex (or hcp) structure in lattice.f90. 


\section{Slip system }

An intersection between slip and basal plane is used in order to sort
the slip system as illustrated in Figures \ref{Fig:BasalPrismSlip}
and \ref{Fig:Pyr&lt;a&gt;&lt;c+a&gt;}. Numbers in Figures \ref{Fig:BasalPrismSlip}
and \ref{Fig:Pyr&lt;a&gt;&lt;c+a&gt;} indicate the sequence of each slip system
in {}``lattice.f90''. In {}``lattice.f90'', No. 4 - 6 for basal
and prism &lt;a&gt; slip do not include (Figure \ref{Fig:BasalPrismSlip}).
In Figure \ref{Fig:Pyr&lt;a&gt;&lt;c+a&gt;}, pyramidal slip &lt;c+a&gt; was used two
criterions to sort the 12 slip systems; i) intersection between pyramidal
slip plane and basal plnae, and ii) &lt;a&gt; direction.

\section{Twin system}

An intersection between twin and basal plane is used in order to sort
the twin system as illustrated in Figures \ref{Fig:TwinType1} and
\ref{Fig:TwinType2}. Numbers in Figures \ref{Fig:TwinType1} and
\ref{Fig:TwinType2} indicate the sequence of each twin system in
{}``lattice.f90''.
