Investigating the ignition response of nitrate ester plasticized polyether(NEPE) propellant under dynam.c extrusion loading is of great significant at least for two cases. Firstly, it helps to understand the m.chanism.and conditions of unwanted ignition inside charged propellant under accident ***, evaluates the risk of a shell crevice in a solid rocket m.tor(SRm. under a falling or overturning scene. In the present study, an innovative visual crevice extrusion experim.nt is designed using a dropweight apparatus. The dynam.c responses of NEPE propellant during extrusion loading, including com.action and com.ression, rapid shear flow into the crevice, stress concentration, and ignition reaction, have been firstly observed using a high-perform.nce high-speed cam.ra. The ignition reaction is observed in the triangular region of the NEPE propellant sam.le above the crevice when the drop weight velocity was 1.90 m.s. Based on the user m.terial subroutine interface Um.T provided by finite elem.nt software LS-DYNA, a viscoelastic-plastic m.del and dual ignition criterion related to plastic shear dissipation are developed and applied to the local ignition response analysis under crevice extrusion conditions. The stress concentration occurs in the crevice location of the propellant sam.le, the shear stress is relatively large, the effective plastic work is relatively large, and the ignition reaction is easy to occur. When the sam.le thickness decreases from.5 m. to 2.5 m., the shear stress increases from.22.3 m.a to 28.6 m.a, the critical value of effective plastic work required for ignition is shortened from.1280 μs to 730 μs, and the triangular area is easily triggering an ignition reaction. The propellant sam.le with a sm.ll thickness is m.re likely to stress concentration, resulting in large shear stress and effective work, triggering an ignition reaction.
