ABSTRACT
The total stress τtotal is additively decomposable into
τ τtotal sτ ta= +t Δ (1)
where τstat and Δτ are static and dynamic stress, respectively. They are associated to the total strain γtotal, additively decomposable into
γ γtotal sγ tat= + Δ (2)
where γstat and Δγ are static and dynamic strain, respectively. The static stress and strain may also be named as prestress (preload) and prestrain, respectively. This model extends the existing nonlinear model given in Blom & Kari (2011) by the prestrain dependence.
