Sommario
Questo scritto prende in esame i principi variazionali nella forma delle ≪hermivariational inequalities≫ e le inclusioni differenziali per vincoli unilaterali nella meccanica analitica. Si deduce come sia pissobile descrivere vincoli unilaterali, in modo generale facendo uso di gradienti generalizzati di Clarke.
Summary
The present paper deals with variational principles in terms of hemivariational inequalities and with differential inclusions for unilateral constraints in analytical mechanics. It is discussed how it is possible to describe one-sided constraints in a very general manner by the help of Clarke's generalized gradient.
