Документ High temperature creep and damage accumulation in cyclically loaded axisymmetrical bodies of revolution(National Technical University "Kharkov Polytechnic Institute", 2010) Breslavsky, D.; Korytko, Yu.; Morachkovsky, O.The paper presents the constitutive equations as well as the data of numerical simulation of creep-damage problems of cyclically loaded and heated axisymmetrical structural members. The procedure of constitutive equations deriving is discussed. The experimental and numerical data have been obtained for cyclically heated specimens made from high quality steel were compared in order to verify the flow rule and damage parameter equation. The problem of creep and damage accumulation in the nipples of the regenerator for catalytic cracking of petroleum was analyzed with consideration of different temperature cycle parameters.Документ Numerical Calculations of Creep Damage at Cyclic Loading by Use of Tensor Damage Parameter Model(Точка, 2013) Breslavsky, D.; Korytko, Yu.; Mietielov, V.; Morachkovsky, O.; Tatarinova, O.Creep of cyclically loaded bodies and their fracture due to creep mechanisms are studied. Creep damage equations are built by use of tensor parameter for titanium alloy. Similar equations were derived for stress cyclic varying using the method of asymptotic expansions and averaging in a period. 2d plane stress problems were solved by FEM and fields of stress, strain, displacement, damage parameter components as well as time to rupture values were obtained
