چکیده

We present a theory that successfully describes the time-dependent mechanical behavior of soft incompressible isotropic polymers in moderately large deformations. The theory is based on the introduction of a generalized measure of strain into the Boltzmann superposition integral.

Semi-analytical Solution for Time-dependent Creep Analysis of Rotating Cylinders Made of Anisotropic Exponentially Graded Material (EGM)

In the present paper, time dependent creep behavior of hollow circular rotating cylinders made of exponentially graded material (EGM) is investigated. Loading is composed of an internal pressure, a distributed temperature field due to steady state heat conduction with convective boundary condition and a centrifugal body force. All the material properties are assumed to be exponentially graded a...

A Modification on Applied Element Method for Linear Analysis of Structures in the Range of Small and Large Deformations Based on Energy Concept

In this paper, the formulation of a modified applied element method for linear analysis of structures in the range of small and large deformations is expressed. To calculate deformations in the structure, the minimum total potential energy principle is used. This method estimates the linear behavior of the structure in the range of small and large deformations, with a very good accuracy and low...

Response Determination of a Beam with Moderately Large Deflection Under Transverse Dynamic Load Using First Order Shear Deformation Theory

In the presented paper, the governing equations of a vibratory beam with moderately large deflection are derived using the first order shear deformation theory. The beam is homogenous, isotropic and it is subjected to the dynamic transverse and axial loads. The kinematic of the problem is according to the Von-Karman strain-displacement relations and the Hook's law is used as the constitutive eq...

Assessment of the Drain Conditions on Variations of the Pore Pressure in Surrounding Soil of the Tunnel

Excess pore pressure under seismic loadings has always been a main concern in geotechnical engineering practices. The phenomenon in soil can cause an effective stress and hence cause the shear strength of the soil to decrease considerably and large deformations to occur in the area. Generally, increases in pore pressure occur in un-drained conditions. If it is formed, its consequences decrease ...

Finite Element Formulations for Fast Computation of Large and Moderately Large Deformations

The paper presents finite element formulations aimed at fast computation of large and moderately large flexible body deformations in the fields of virtual reality technology and multibody dynamics. In many areas of application, virtual reality requires real-time or nearly real-time simulation of deformable objects’ behaviour, quite often with deformations involving large local rotations. The we...
