The results show that strength of NEPE solid propellant under multi-axis stress state is related to strain; octahedral shear stress nonlinearly increases with the average main stress.

研究表明，多轴应力状态下NEPE固体推进剂强度与应力相关，八面体剪应力随平均主应力的增加呈非线性增加；NEPE推进剂的破坏强度随拉伸速率的增加而提高。

One day--maybe not next year or in five years, but eventually--the Big Mac will flatline in the U.S. The evidence: In the past four years McDonald's has averaged only 1% annual same-store sales growth, trailing the 4% average for its main burger rivals.
