Detailed Description

A class representing a damage model.

The PeriDigmDamageModel class represents a damage model that is used to simulate the deformation and failure of material in a peridynamic simulation. Currently, only one type of damage model is supported: critical stretch.

GetStretchFromEnergyReleaseRate()

double PeriDigmDamageModel::GetStretchFromEnergyReleaseRate ( double youngs_modulus, double poissons_ratio, double horizon, double energy_release_rate )

static

Computes the stretch value from an energy release rate.

This static method computes the stretch value from an energy release rate and other material properties.

Parameters

youngs_modulus	The Young's modulus of the material.
poissons_ratio	The Poisson's ratio of the material.
horizon	The horizon parameter used in the peridynamic simulation.
energy_release_rate	The energy release rate.

Returns

The computed stretch value.

InitFromEnergyReleaseRate()

void PeriDigmDamageModel::InitFromEnergyReleaseRate	(	double	youngs_modulus,
		double	poissons_ratio,
		double	horizon,
		double	energy_release_rate )

Initializes the damage model from an energy release rate.

This method initializes the damage model by computing the critical stretch value from an energy release rate and other material properties.

Parameters

youngs_modulus	The Young's modulus of the material.
poissons_ratio	The Poisson's ratio of the material.
horizon	The horizon parameter used in the peridynamic simulation.
energy_release_rate	The energy release rate.

WriteInputFile()

void PeriDigmDamageModel::WriteInputFile	(	std::ostream &	os,
		int	damage_model_id )

Writes the damage model to an input file.

This method writes the damage model to an input file.

Parameters

os	The output stream to which the input file is written.
damage_model_id	The index of the damage model.
