Abstract: A family of n-sub-step composite time integration methods, which employs the trapezoidal rule in the first $$n-1$$ sub-steps and a general formula in the last one, is discussed in this paper. A universal approach to… read more here.

Abstract: A SIMPLE UNIFIED SET OF DISPLACEMENT AND VELOCITY APPROXIMATIONS IS PRESENTED TO EXPRESS VARIOUS TWO-STAGE COMPOSITE TIME INTEGRATION SCHEMES. BASED ON THE UNIFIED APPROXIMATIONS, TWO NOVEL SETS OF OPTIMIZED PARAMETERS ARE NEWLY PROPOSED FOR THE… read more here.
