Computational Design Of Nonlinear Stress-Strain Of Isotropic Materials, Askhad M.Polatov, Akhmat M. Ikramov, Daniyarbek Razmukhamedov
Chemical Technology, Control and Management
The article deals with the problems of numerical modeling of nonlinear physical processes of the stress-strain state of structural elements. An elastoplastic medium of a homogeneous solid material is investigated. The results of computational experiments on the study of the process of physically nonlinear deformation of isotropic elements of three-dimensional structures with a system of one- and double-periodic spherical cavities under uniaxial compression are presented. The influence and mutual influence of stress concentrators in the form of spherical cavities, vertically located two cavities and a horizontally located system of two cavities on the deformation of the structure are investigated. Numerical …

Study The Effect Of Damping Change During The Dynamic Analysis Of A Reinforced Concrete Bridge With Neoprene Cushions, Mais Ghassoun
Emirates Journal for Engineering Research
The damping ratio has a important effect on the dynamic behavior of the bridges. and it is customary when designing to assume it as a predetermined fixed value independent of the response amplitude and frequency of the structure . A lot of experimental research worked on identifying them, but the dependence of damping and other dynamic characteristics of vibration amplitudes and their impact on responses and the results of the analysis need more scrutiny and simulation due to the difficulty of conducting vibration experiments for structures of realistic dimensions and large weights such as a RC bridge, which necessitated a …
