Abstract

Exfoliation the not extensible flexible stiffener heated up to the set temperature is investigated in conditions of a plane problem thermoelasticity. The flexible stiffener is placed at edge of the semi-infinite plates in conditions ideal thermal contact and action the stretching loading on the plate. Development of localized zones of prefracture (the weakened contact) is precede to separation the stiffener in vicinities of her ends. They can correspond to regions of damages, plastic deformation, partial break of connection and another precedes. On area outside of zones of prefracture the perfect mechanical contact is remaining. The analytical decision of a problem is shown to problem Koshy for differential equation of the first order and realized its numerical analysis. Physically correct limited stresses and deformations are received in all points of a composition. Tangents stresses also satisfy to relationship of pair law. Basic part of loading from reinforcements to plate is transfer in neighbourhood of reinforcement ends. Interference of power and temperature loadings on flexible stiffener separation is investigated.

Key words: reinforcement, exfoliation, plane problem, zone of prefracture.
