The cylinder, rings and plates are made of 2024-T3 sheet aluminum alloy and have the following material properties (according to AMS 4037 property data):
| Cylinder, Ring, and Plate Material Properties | |
|---|---|
| Young's Modulus (GPa) | E = 73 |
| Poisson's Ratio (ν) | 0.33 |
The plastic part of the material is modeled using the von Mises yield criteria coupled with an isotropic hardening (TB,PLAS,,,,BISO), described by a bilinear stress-strain curve with the following constants:[a]
| Plastic Material Properties | |
|---|---|
| Yield Stress (MPa) | σy = 268.9 |
| Tangent Modulus (MPa) | ET = E / 1000 = 73 |
The tangent modulus is assumed, as no data is provided for this property in the reference information. Because the reference [2] does not provide all necessary material data, some of the material data are obtained from other publications detailing the properties of the same material.
