Sample interview questions: How do you approach the assessment and selection of materials for space system structural stability?
Sample answer:
Assessment and Selection of Materials for Space System Structural Stability
Methodology:
1. Establish System Requirements and Constraints:
* Define load requirements, temperature ranges, radiation exposure, and other environmental factors.
* Determine material properties required for specific structural components, such as strength, stiffness, and durability.
2. Material Screening and Evaluation:
* Identify potential candidate materials based on initial property requirements.
* Conduct thorough testing to evaluate material properties, including mechanical (tensile, compressive, shear), thermal (coefficient of thermal expansion, thermal conductivity), and radiation resistance.
* Consider factors such as material availability, cost, and manufacturability.
3. Structural Modeling and Analysis:
* Develop computational models using Finite Element Analysis (FEA) to simulate material behavior under load conditions.
* Determine structural integrity, stress concentrations, and potential failure modes.
* Optimize material selection and structural design to meet system performance goals.
