Determination of negative skin friction force and The neutral plan is one the challenges which face geotechnical engineers. Unfortunately, decreases bearing capacity pile because extra compressive on pile. In this research, a 3D FE models were used to investigate behavior single group in soft soil for surcharge load as embankment fill. And what are differences that will happen group. For fill l...

in this paper, using numerical methods and test results, the behavior of reinforced concrete beams strengthened with fiber-reinforced polymers (frp) is investigated. in the numerical analysis, the concrete damaged plasticity model is used for considering the nonlinear behavior and strain softening of concrete. the abaqus finite element program is utilized for the analysis of 12 flexural beams s...

in present research, 17 centrifuge tests have been conducted to study the effect of various parameters such as the number of piles, the distance between piles, gradation and thickness of the granular layer on the load-settlement behavior of a pile raft system. the results showed the importance of granular layer to reduce the settlement of non-connected pile raft system when the roles of piles a...

With the promotion of soft viscoelastic materials in field flexible bionic robots, behavior sliding friction between and rigid such as metals has attracted great attention. In this study, research object was silicone, a method combining dynamic force testing technique non-contact optical for deformation strain proposed to study frictional silicone effect tooth structure surface on friction. We ...

This paper deals with an analytical approach to predict the nonlinear buckling behavior of functionally graded graphene-reinforced composite laminated cylindrical shells under axial compressive load surrounded by Pasternak’s elastic foundation in a thermal environment. Piece-wise functionally graded graphene-reinforced, composite layers are sorted with different types of graphene distribution. ...
