DmgLib

Purpose

value and slope of damage evolution function FNAME

Synopsis

y = DmgLib (Fname)

Description

DMGLIB value and slope of damage evolution function FNAME
  the function returns the value and slope of the damage evolution function FNAME;
  the library contains the following normalized functions for damage evolution
    None  : no damage
    MBeta : modified beta cumulative distribution with the following parameter relation
            a = dp(2), b = dp(1)*dp(2) for dp(1)>1 and a = dp(2)/dp(1), b=dp(2) otherwise
    OBeta : beta cumulative distribution      with parameters dp(1) and dp(2)
    Wbl   : Weibull cumulative distribution   with parameters dp(1) and dp(2)
    Logn  : lognormal cumulative distribution with parameters dp(1) and dp(2)
    Bilin : bilinear   function with parameters dp(1)-dp(3)
    Trilin: trilinear  function with parameters dp(1)-dp(5)
