Stress Concentrators in Continuous Deformable Bodies

Vahram Hakobyan is the author of more than 130 scientific papers in the field of contact and mixed problems of the theory of elasticity and viscoelasticity. The author of two monographs "Stress Concentration Near Defects in Homogeneous And Compound Bodies" and "Mixed Boundary Value Problems on Interaction of Continuum Deformable Bodies with Different Types Stress Concentrators", Prof. Hakobyan was the first to obtain closed solutions for some problems both for a homogeneous and piecewise homogeneous plane with defects, and a number of mixed axisymmetric problems for a composite space with cracks. He worked for thirteen years as a director of the Institute of Mechanics of the National Academy of Sciences (Republic of Armenia).
