2.11.15. output_stress_tensor{ }

Calling sequence

strain{ output_stress_tensor{ } }

Properties

• usage: \(\mathrm{\textcolor{Dandelion}{conditional}}\)

• items: maximum 1

Dependencies

• This keyword is allowed if one of pseudomorphic_strain{ } and minimized_strain{ } is defined.

Functionality

output (symmetric) stress tensor : \(\ \sigma_{ij} = C_{ijkl}\ \varepsilon_{kl}\) [GPa]

Example

strain{
    output_stress_tensor{}
    pseudomorphic_strain{}
}

Nested keywords

crystal_system

Calling sequence

strain{ output_stress_tensor{ crystal_system } }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional}}\)

• type: choice

• values: yes or no

• default: no

Functionality

output stress tensor in crystal coordinate system

Example

strain{
    output_stress_tensor{
        crystal_system = yes
    }
    pseudomorphic_strain{}
}

simulation_system

Calling sequence

strain{ output_stress_tensor{ simulation_system } }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional}}\)

• type: choice

• values: yes or no

• default: yes

Functionality

output stress tensor in simulation coordinate system (useful if simulation coordinate system differs from crystal coordinate system)

Note

The ordering of the stress tensor components is: \(\sigma_{xx},\ \sigma_{yy},\ \sigma_{zz},\ \sigma_{xy},\ \sigma_{xz},\ \sigma_{yz}\)

Example

strain{
    output_stress_tensor{
        simulation_system = no
    }
    pseudomorphic_strain{}
}

strain{ output_stress_tensor{ boxes } }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional}}\)

• type: choice

• values: yes or no

• default: no
