Split Runge-Kutta method for simultaneous equations
Runge-Kutta method; simultaneous equations; missile simulations
Consider two simultaneous first order differential equations x' (t)=F(x ,y, t), y'(t)=G(x,y,1). Runge-Kutta type integration methods are developed which allow different integration steps to be used for these equations. These methods retain the...

Representation of long-time creep in a pure-gum rubber vulcanizate
Rubber: creep of; long-time creep of; mechanical properties of; relaxation of; time effects in.
Creep may be expressed as deltaE/E1 = A log t + B(t-1) where deltaE is the increase of elongation above E1 the one-minute value, during the time t. The initial slope of a plot of deltaE/E1 against log t is A, a measure of physical creep. The limit...
