getDelamTime: Generate interface debonding times

Description

Generate individual defect times for particle debonding

Usage

getDelamTime(E, stress, param, inF = 0.5, outF = 0.65)

Arguments

E

object of class "oblate", "prolate", "cylinders", "spheres"

stress

stress level

param

simulation parameter vector, see details

inF

weightening factor for inner defect projection

outF

weightening factor for outer defect projection

Value

numeric, the individual debonding time

Details

This kind of failure time (time of debonding from the metal matrix structure) roughly depends on the projected area of the object, the applied overall stress level and whether the object lies in the interior of the simulation box or hits one of the box boundaries. The parameter vector is made up of six parameters where the second and third parameters are used to simulate the defect type crack, see getCrackTime. The order is as follows: \(p1\) probability of already materialized defects, scale factor \(p2\), shape factor \(p3\), shift parameter \(p4\) of log times, the slope \(p5\) and \(p6\) denoting the standard deviation of the random errors of the log times. Only the last three parameters \(p4,p5,p6\) are used to determine the defect time for debonding of the considered object.
