Struct MuscleMaterial 

Source 
pub struct MuscleMaterial {
    pub max_isometric_force: f64,
    pub optimal_fiber_length: f64,
    pub pennation_angle: f64,
    pub vmax_factor: f64,
    pub passive_stiffness: f64,
}
Expand description

Hill three-element muscle model.

Active force is generated by the contractile element (CE); total force combines the active CE with a passive elastic element (PE).

Fields§

§max_isometric_force: f64

Maximum isometric force F0 (N).

§optimal_fiber_length: f64

Optimal fiber length L0 (m) at which active force is maximal.

§pennation_angle: f64

Pennation angle at optimal length (radians).

§vmax_factor: f64

Maximum shortening velocity Vmax = k * L0 (fiber lengths per second).

§passive_stiffness: f64

Passive tissue stiffness coefficient (Pa).

Implementations§

Source§

impl MuscleMaterial

Source

pub fn biceps() -> Self

Human biceps brachii defaults.

Source

pub fn force_length_factor(&self, length: f64) -> f64

Force-length factor FL(l) — bell-shaped function around L0.

Returns a value in [0, 1].

Source

pub fn active_force(&self, activation: f64, length: f64) -> f64

Active force produced by the contractile element.

  • activation – neural activation in [0, 1].
  • length – current fiber length (m).
Source

pub fn passive_force(&self, length: f64) -> f64

Passive elastic force from parallel element (N).

Source

pub fn total_force(&self, activation: f64, length: f64) -> f64

Total muscle force (N) = active + passive.

Source

pub fn tissue_type(&self) -> TissueType

Tissue type classification.
