\title{Critical area}
\usage{
areaCrit(vickers, stress, factor = 1.56)
}
\arguments{
\item{vickers}{specific Vickers hardness}

\item{stress}{stress level}

\item{factor}{specific material dependent factor, default set to \code{1.56} for inner defects}
}
\value{
critical area in \eqn{\mu m^2}
}
\description{
Calculate critical area
}
\details{
The critical area (see reference below) is roughly defined by the projected defect area
above which the specific material defect becomes particularly hazardous for the failure
of the whole specimen.
