I want to find the postdoc position. My investigation on a plasticity theory, limiting state investigations, magnetoelastic, piezoelectric and ferromagnetic plates and shells vibrations frequences investigations by exact space treatment. I have investigate the elastic-plastic problems of conical and cylindrical pipes with different plasticity criterias. I have define the elastic and plastic regions of mentioned problems. I have investigate the limiting state problem of finite conical and cylindrical bodies. In my PhD disseratation I have investigate the junction strength problems for linear and nonlinear compound wedge shaped thin plates. Dependent from wedges angles I have defined the less stress and stress concentration regions. Less stress region - it's region where stresses going to the zero and concentration region when stresses going to the infinity. As nonlinear material I take the power law hardening materials. I have show that the Reissner hypothesis have privelegeous in the mentioned problems than the Kirkhoff hyphotesis. Also I have investigate the compound conical pipes junction strength problem. And I have define the optimum strength state of the mentioned joint. The mentioned problems I have solved for nonhomogeneous materials (functionally graded materials).
