Struct TwoWaySMA 

pub struct TwoWaySMA {
    pub training_cycles: usize,
    pub max_trained_strain: f64,
}

Two-way shape memory effect (TWSME) model.

After repeated thermomechanical training cycles, SMAs develop an intrinsic martensite preferred orientation that allows them to actuate bidirectionally without external stress.

Fields

training_cycles: usize

Number of completed thermomechanical training cycles.

max_trained_strain: f64

Maximum trained strain achievable (dimensionless).

Implementations

impl TwoWaySMA

pub fn new(training_cycles: usize, max_trained_strain: f64) -> Self

Create a new two-way SMA model.

pub fn nitinol() -> Self

Standard Nitinol two-way model.

pub fn train(&mut self, cycles: usize)

Add training cycles and return new total.

pub fn trained_strain(&self) -> f64

Recoverable trained strain after training_cycles cycles.

The TWSME strain saturates with an empirical logarithmic law: ε_trained = ε_max · (1 − exp(−n / 10)) where n is the number of training cycles.

pub fn saturation_fraction(&self) -> f64

Fraction of maximum trained strain achieved.
