We conceder constitutive laws with internal state variable and damage,with arguments mathematicals and we have used this to prove the existence and uniqueness of a weak solution for the problem.m 􀀀 􀀀d tF􀀀 d ¤ ,C􀀀rR¯􀀀fr,CrS 􀀀 ,Tyl 􀀀d 􀀀 T A 􀀀 ry t ,TyVAWm 􀀀 T zl 􀀀 T§C􀀀r ¤rhkþ 􀀀 : Ty Atf Amlhermo-electro-viscoelastics, internal state variable, damage,the bilateral contact, Tresca’s friction, weak solution, fixed point theorem.Master
