title: 'FCGR: Fatigue Crack Growth in Reliability'
version: 1.2-0
doi: 10.32614/CRAN.package.FCGR
abstract: Fatigue Crack Growth in Reliability estimates the distribution of material
  lifetime due to mechanical fatigue efforts. The 'FCGR' package provides simultaneous
  crack growth curves fitting to different specimens in materials under mechanical
  stress efforts. Linear mixed-effects models with smoothing B-Splines and the linearized
  Paris-Erdogan law are applied. Once defined the fail for a determined crack length,
  the distribution function of failure times to fatigue is obtained. The density function
  is estimated by applying nonparametric binned kernel density estimate ('bkde') and
  the kernel estimator of the distribution function ('kde'). The results of Pinheiro
  and Bates method based on nonlinear mixed-effects regression ('nlme') can be also
  retrieved. The package contains the crack.growth(), PLOT.cg(), IB.F(), and Alea.A
  (database) functions.
