Generate individual defect times for particle debonding

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

`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

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.

numeric, the individual debonding time
