A solid rocket motor is one of the critical components of solid missiles, and its life and reliability mostly depend on the mechanical behavior of a composite solid propellant (CSP). Effective mechanical properties are critical material constants to

The relaxation modulus of heterogeneous propellants permits evaluating the structural integrity and life of a solid rocket motor. Its governing factors were investigated by the Voronoi cell finite element method (VCFEM) at the microscopic level. The

Security work is always the most important part of teaching and training in school. The accidents have an adverse effect on the normal work. Although accidents have the characteristics of suddenness, harmfulness and inevitability. They also have rule

The BOPPPS model is a new teaching model with six stages. This model is more suitable for some independent courses, but for some of the more complex courses. This model is not conducive to the setting, which is easy to cause. It may fragment course k

Accidents are characterized by suddenness, danger, and universality. Accidents not only cause casualties and property losses, but also seriously affect the normal work and construction of a unit. Therefore, for a unit with high safety requirements, s

A progressive collapse of a RC frame structure may be initiated by an event that damages one member of the structure. FRP is widely used in the field of structural reinforcement for its high strength ratio, convenient construction and corrosion resis
