◆ characteristicLength()

double GmpMaterialIsotropicDamage::characteristicLength	(	const GmElement *	e,
		GmValueAccessor *	nodeAcc,
		bool	type = `false`
	)		const

virtual

Returns the characteristic length.

Returns the characteristic length lch Type = true enables to compute the characteristic length according to Kurumatani et al. 2016 while Type = false (default) returns the traditional way to compute the characteristic length equal to lch = sqrt(Ae) for 2D and lch = pow(Ae, 1/3) for 3D.

virtual

Returns a pointer to the material attribute map, built when the function is called for the first time.

This table includes the attributes treated by the base class, GmpMechanicalMaterial, adding
