Predictor Step

Linearization of the stiffness matrix (predictor step)

{}_{0}^{t}K ∆_{0} φ = {}^{t + ∆ t}f_{ext} - {}_{0}^{t}f_{int}

K	Stiffness matrix of the previous time step
^t+Δ^tf_ext	External forces increased by a further load step
₀^tf_int	Internal forces of the previous time step
ϕ	Strain
