After Fitzpatrick's seminal work MR 1009594, it is known that in a real Banach space V any
maximal monotone operator α: V →\mathcal P (V^ ′) may be given a variational …

A nonlinear boundary value problem arising from continuum mechanics is considered. The
nonlinearity of the model arises from the constitutive law which is described by means of the …

In the present work, we address a nonlinear boundary value problem that models frictional
contact with prescribed normal stress between a deformable body and a foundation. The …

We propose a modification of the Hamiltonian formalism which can be used for dissipative
systems. This work continues a previous work on Hamiltonian inclusions and advances by …

We study a bilateral contact model with power-law friction and a regularized version of it as
well, a regularization of the friction law being considered. The behavior of the material is …

In this paper we investigate a system of coupled inequalities consisting of a variational–
hemivariational inequality and a quasi-hemivariational inequality on Banach spaces. The …

We study a class of frictional contact problems with prescribed normal stress, for nonlinearly
elastic materials. Using a bipotential which depends on the constitutive map and its Fenchel …

We consider a unilateral contact model for nonlinearly elastic materials, under the small
deformation hypothesis, for static processes. The contact is modeled with Signorini's …

A contact model with Tresca's friction law is considered, the behavior of the material being
modeled by the subdifferential of a convex constitutive map. Using a separable bipotential …

In Gurson's footsteps, different authors have proposed macroscopic plastic models for
porous solid with pressure-sensitive dilatant matrix obeying the normality law (associated …
