Verification of Composite Laminates under Cryogenic Thermo-Mechanical Loading
Proposed activities:
 
  • Assess and identify the limitations of the commonly used approach for strength verification of composite laminates under cryogenic thermo-mechanical environment (including modelling, failure criteria with supporting test methods to determine allowable values).
  • Assess relevance of stacking sequences of plies in the laminate for resistance against cryogenic thermo-mechanical loading.

    Numerical Simulations for Spacecraft Catastrophic Disruption Analysis

    While the vast majority of space debris still stems from explosion events of satellites and rocket upper stages, current forecasts state that collisions, such as those between the Cosmos 2251 and Iridium 33 satellites in 2009, will play a dominant role in the mid-term future when a critical spatial density of satellites has been reached. In order to assess the risks emanating from space debris, a deeper understanding of the formation and residence time of breakup debris in orbit is essential for operational activities.
