oedometer_create_data: Create oedometer time-sample height data for single load step

In GJMeijer/soilmech: R functions and plots for Soil Mechanics teaching

Create oedometer time-sample height data for single load step

Description

Create some time - sample height oedometer data, given known soil properties, for a single load step

Usage

oedometer_create_data(
  t = NULL,
  h0 = 20 * 0.001,
  dsigmav = 20000 * 1e+06,
  mv = 5e-06,
  cv = 1e-08,
  Calpha = 0.01,
  Tvalpha = 10^0.2
)

Arguments

t	array with time steps. If not defined, a wide range is assumed
h0	initial sample height [m]
dsigmav	increase in vertical stress [Pa]
mv	coefficient of compressibility [m^2/N]
cv	coefficient of consolidation [m^2/s]
Calpha	creep strain per log10-cycle of time. Creep is only added after primary consolidation is (almost) finished. A small smoothing is applied to smoothen the sudden jump in gradient of settlement
Tvalpha	value of normalised strain at which creep stats to be included

Value

tibble with field for time ('t', in seconds) and current sample height ('h', in meters)

Examples

#get data
df <- oedometer_create_data()

#plot data - log scale for time
ggplot2::ggplot() +
  ggplot2::geom_line(
    data = df,
    ggplot2::aes(x = t, y = h)
  ) +
  ggplot2::scale_x_log10()
