MODELLING OF STRESS STATE OF ELASTIC MEDIUM CONTAINING PERFECTLY AND IMPERFECTLY BONDED THIN INCLUSIONS AND OVERLAYS
Keywords:
thin inclusion, delaminating, overlay, imperfect contact, friction, boundary element methodAbstract
This study considers modelling of two-dimensional stress state of solids containing thin elastic inclusions. In modeling the coupling principle for continua of different dimension is utilized. Basing on the model of inclusion under the perfect contact three other models of imperfect contact are developed. The simplest one is a model of thin inclusion, which is completely delaminated at certain segments. Two other models take into account a smooth contact between inclusion and a solid, and also a contact with friction. The developed models are easy to introduce into the used boundary element approach. The model of inclusion, completely debonded at one face, is also used in modeling of solids with thin elastic overlays or stringers.Downloads
