## SectionCut.get\_transformed\_sectional\_properties\_matrix(properties, position, axes\_type, matrix\_type, matrix\_format)

Transform the global mass or stiffness matrix to the given point and rotate it by the given angle, for a specific format.

### Parameters

- properties: All sectional properties of the equivalent beam properties calculation.
- position: The point to which the matrix is transformed. Valid options: “origin”, “center of gravity”, “shear center”, and “elastic center”.
- axes\_type: Output the matrix in this axes system. Valid options: “global”, “elastic axes”, and “principal inertia axes”.
- matrix\_type: The type of the matrix. Valid options: “mass\_matrix” and “stiffness\_matrix”.
- matrix\_format: The format of the transformed matrix. Valid options: “default” or “ansys” (Ansys preintegrated composite beam).

### Returns

The transformed matrix (6,6).

### Usage

```pycon
>>> result = section_cut.compute_equivalent_beam_properties(check_status=True)
>>> transformed_stiffness_matrix = section_cut.get_transformed_sectional_properties_matrix(
        properties=result.properties,
        position="elastic center",
        axes_type="elastic axes",
        matrix_format="ansys",
        matrix_type="stiffness_matrix"
    )
>>> transformed_mass_matrix = section_cut.get_transformed_sectional_properties_matrix(
        properties=result.properties,
        point="center of gravity",
        axes_type="principal inertia axes",
        format="default",
        matrix_type="mass_matrix"
    )

```
