A thermodynamically consistent phase-field framework for viscoelastic fatigue fracture with dissipated-energy-driven toughness degradation

· · 来源:tutorial导报

Welcome to Edition 8.32 of the Rocket Report! The big news this week is NASA's shake-up of the Artemis program. On paper, at least, the changes appear to be quite sensible. Canceling the big, new upper stage for the Space Launch System rocket and replacing it with a commercial upper stage, almost certainly United Launch Alliance's Centaur stage, should result in cost savings. The changes also relieve some of the pressure for SpaceX and Blue Origin to rapidly demonstrate cryogenic refueling in low-Earth orbit. The Artemis III mission is now a low-Earth orbit mission, using SLS and the Orion spacecraft to dock with one or both of the Artemis program's human-rated lunar landers just a few hundred miles above the Earth—no refueling required. Artemis IV will now be the first lunar landing attempt.
