Description
Heat shield tiles on spacecraft are made of ceramic fiber, a light, porous material whose strength is hard to predict. Yiming Wang and co-authors build a computer model of how these tiles bend, yield, and crack. The model starts from classic failure rules for layered materials and adds a damage factor for the tile's special stacking direction.
They coded the model into the ABAQUS engineering package and ran it under pressing, pulling, and shearing loads. Simulated stress curves tracked the lab curves closely, with errors under eighteen percent. A fine indentation test at millimeter scale confirmed the match, with depth errors under twelve percent. The authors offer the model as a reliable way to forecast tile behavior in the harsh conditions of flight.
