Kapton

Kapton Class

class Kapton(gamma_eff: float = 0.6, initial_density: float = 1.33, released: bool = False)

Initializer of the Kapton class.

Parameters:

gamma_eff – \(\Gamma_{eff}\) is the updated Mie-Grüneisen (MG) parameter \(\Gamma\) for the linear reference of the Mie-Grüneisen (MGLR) model, that assumes the release path can be accurately reproduced with constant \(\Gamma\) along nearly its entirety. More details on the process of calculating the \(\Gamma_{eff}\) given experimental data can be found in [1]. Default value for Kapton \(\Gamma_{eff}=0.6\).
initial_density – Density of Kapton material at ambient environment conditions found here. Default Value \(1.33\). Units: \(g/cm^3\).
released –
Boolean parameter indicating whether the reflected shock produced at the interface of the current material with the next is a rarefaction or a reshock.
- If True, then the algorithms assumes that the material undergoes release and compute the release part of the isentrope.
- If False, then the algorithm assumes the material will be reshocked and computed the respective part of the isentrope.
Default value: False.

Kapton.nominal_hugoniot: Hugoniot: This attribute represents the deterministic value all possible shocked states of the Kapton material. Since we did not have access to experimental data to learn the relationship between shock \((U_s)\) and particle velocities \((u_p)\) of the Kapton Hugoniot, it is extracted from the hugoniot command of HYADES hydrocode [2]. The extracted data can be found inside the kapton_hugoniot.txt file inside the data folder of the material database module.

Kapton.hugoniots_list: list[Hugoniot]: A list of possible material Hugoniots. Since Kapton is deterministic it contains the data for only one Hugoniot curve.
