Arguments

shape

Optional input argument that dictates shape-type, if desired, for generalized shapes.

x_body

Vector containing x-axis body (m) shape data.

y_body

Vector containing y-axis body (m) shape data.

z_body

Vector containing z-axis body (m) shape data.

radius_shell

Radius of shell (m).

shell_thickness

Optional shell thickness (m).

g_fluid

Optional density contrast for fluid-like body.

density_fluid

Optional density for fluid-like body (kg/m³).

h_fluid

Optional sound speed contrast for fluid-like body.

sound_speed_fluid

Optional sound speed for fluid-like body (m/s).

g_shell

Density contrast for the shell.

density_shell

Optional density for the shell (kg/m³).

h_shell

Sound speed contrast for the shell.

sound_speed_shell

Optional sound speed for the shell (m/s).

E

Young's modulus (Pa) of the shell material.

G

Shear modulus (Pa) of the shell material.

K

Bulk modulus (Pa) of the shell material.

nu

Poisson's ratio (Dimensionless) of the shell material.

theta_shell

Object orientation relative to incident sound wave.

ID

Optional metadata entry.

theta_units

Units used for orientation. Defaults to "radians".

length_units

Units used for position vector. Defaults to "m".

Value

ESS-class object
