Research on influence of diameter ratio and length-diameter ratio on structural integrity of solid propellant under temperature loading
To investigate the influence of number m and length-diameter ratio on structural integrity of solid propellant under temperature loading
the thermoviscoelastic large deformation incremental constitutive equation was derived from Total Lagrangian method.Nine different numbers m and eight length-diameter ratios for calculation 72 models were selected to measure the effects on the structural integrity.The results show that
number m and length-diameter ratio have cooperative effects on the maximum value of equivalent Von Mises stress and strain.If the length-diameter ratio is larger than 3
it's concluded that the maximum value of equivalent Von Mises stress and strain are mainly determined by number m of solid propellant.
