Stability of an explicit time-integration algorithm for hybrid tests, considering stiffness hardening behavior

An explicit unconditionally stable algorithm for hybrid tests, which is developed from the traditional HHT-α algorithm, is proposed. The unconditional stability is first proven by the spectral radius method for a linear system. If the value of α is selected within [-0.5, 0], then the algorithm is sh...
