Stress evaluation of automotive steel road wheel under radial load.

Evaluation of stress distribution in bolted steel angles under tension

The stress distribution in the vicinity of connections in a bolted steel angle is non-uniform because of the coupled effects of connection eccentricity, shear lag and stress concentrations. Although, some researchers have attempted finite element analysis, stipulations in various codes and specifications regarding the design of angle tension members are primarily based on the experimental studi...

Influence of Stress Concentration Factor on Magnetic Memory Effect of Steel Samples under Dynamic Tension Load

Under the excitation of geomagnetic field, normal component of surface scattering magnetic field intensity Hp(y) changes of steel tensile samples with different stress concentration factors α were studied. Constant amplitude sinusoidal tensile load cycles were applied on 18CrNi4A steel plate samples whose α were respectively 1, 3 and 5. Then the correlation of Hp(y) value changes with loading c...

Stainless steel pitting and early-stage stress corrosion cracking under ultra-low elastic load

Numerical Comparison of Pavement Distress Due to Moving Load under Dual-wheel Tandem and Tridem Axles

Finite element method in pavement analysis is a type of mechanistic analysis that has widely been used by road and transportation engineers these days. This method is used with related programs such as ABAQUS/CAE which is one of the powerful software on this task. Modeling in this software has been developed from 2D static models to 3D dynamic models which are closer to reality due to the more ...

Nonlinear Vibration of Functionally Graded Cylindrical Shells under Radial Harmonic Load

In this paper, the nonlinear vibration of functionally graded (FGM) cylindrical shells subjected to radial harmonic excitation is investigated. The nonlinear formulation is based on a Donnell’s nonlinear shallow-shell theory, in which the geometric nonlinearity takes the form of von Karman strains. The Lagrange equations of motion were obtained by an energy approach. In order to reduce the syst...
