Enum Constant Detail

VonMisesStress

public static final FemModel.StressStrainMeasure VonMisesStress

von Mises stress, as defined in https://en.wikipedia.org/wiki/Von_Mises_yield_criterion. It is equal to sqrt(3 J2), where J2 is the second invariant of the average deviatoric stress.

VonMisesStrain

public static final FemModel.StressStrainMeasure VonMisesStrain

von Mises strain, as defined in http://www.continuummechanics.org/vonmisesstress.html, which is equivalent to https://dianafea.com/manuals/d944/Analys/node405.html. It is equal to sqrt(4/3 J2), where J2 is the second invariant of the average deviatoric strain.

MAPStress

public static final FemModel.StressStrainMeasure MAPStress

Absolute value of the maximum principle stress.

MAPStrain

public static final FemModel.StressStrainMeasure MAPStrain

Absolute value of the maximum principle strain.

MaxShearStress

public static final FemModel.StressStrainMeasure MaxShearStress

Maximum shear stress, given by

 max (|s0-s1|/2, |s1-s2|/2, |s2-s0|/2)
 

where s0, s1, and s2 are the eigenvalues of the stress tensor.

MaxShearStrain

public static final FemModel.StressStrainMeasure MaxShearStrain

Maximum shear strain, given by

 max (|s0-s1|/2, |s1-s2|/2, |s2-s0|/2)
 

where s0, s1, and s2 are the eigenvalues of the strain tensor.

EnergyDensity

public static final FemModel.StressStrainMeasure EnergyDensity

Render as a color map showing the strain energy density.

Method Detail

values

public static FemModel.StressStrainMeasure[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (FemModel.StressStrainMeasure c : FemModel.StressStrainMeasure.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static FemModel.StressStrainMeasure valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
