Peierls Creep

Strain rate for low-temperature, plastic deformation mechanism that corresponds to dislocation glide at high stress (differential stress larger than 200 MPa).

Usage

peierls_creep(
  stress,
  temperature,
  model = c("Goetze1979", "Demouchy2013", "Mei2010"),
  sim = 1e+06
)

Arguments

stress

Differential stress in MPa or units object

temperature

Temperature in Kelvin or units object

model

character. Model to be used, one of "Goetze1979" (Goetze and Evans, 1979), "Demouchy2013" (Demouchy et al, 2013), and "Mei2010" (Mei et al., 2010)

sim

integer. Number of Monte Carlo simulations.

Value

Strain rate in 1/s
