Compressive Creep of Virgin HDPE Using Equivalent Strain Energy Density Method
Journal of Materials in Civil Engineering, 2010This paper presents a predictive model for compressive creep behavior of high-density polyethylene (HDPE) commonly used to manufacture polymeric piling and geosynthetics. Accelerated methods to predict the tensile creep of polymers are already available. In this paper, a method to predict the compressive creep of viscoelastic polymers is proposed based

Equivalent-strain method and crack vertex advance
Soviet Materials Science, 1989An approximate approach is proposed for determining the opening of a crack and the size of the plastic zone arising ahead of the crack front for bounded bodies. The basis of the approach is the equivalent loaded-state method. The method has been tested in solving various standard problems and has been found very effective.

Volume 7A: Structures and Dynamics, 2019
Abstract When considering mechanical components that are subjected to complex loading conditions, it is difficult to achieve accurate predictions of low-cycle fatigue life. For multiaxial and non-proportional loads, the principal strain directions vary in three-dimensional space with time.

Structural Multi-Damage Identification Based on Modal Strain Energy Equivalence Index Method
International Journal of Structural Stability and Dynamics, 2014In order to solve structural multi-damage identification problems, a damage detection method based on modal strain energy equivalence index (MSEEI) is presented. First, an accurate expression of modal strain energy (MSE) before and after damage occurs is given.

A new method of characterizing equivalent strain for equal channel angular processing
Journal of Central South University of Technology, 2009In order to establish the quantitative relationship between equivalent strain and the performance index of the deformed material within the range of certain passes for equal channel angular processing (ECAP), a new approach to characterize the equivalent strain was proposed.

In this study, an efficient fatigue life estimation approach is proposed based on an equivalent solid model, along with two stress concentration factors, instead of a lattice model to simplify simulations for the strain-life method. One of the stress concentration factors accounts for the stress concentrations at the strut joints in lattice structures

Thin-Walled Structures, 2020
Abstract Large welding-induced distortions are inevitably generated in a thin-plate welded joint due to its weak stiffness. In this study, an equivalent thermal strain method based on inherent strain theory is proposed to predict the welding deformation of thin plates.

For the title problem, we prove that not only the displacements but also the stresses of the enhanced assumed strain (EAS) elements calculated from the strains are identical to those of the corresponding hybrid-elements, at least at the Gauss integration points provided the spaces of the trial functions for enhanced assumed strains and for assumed ...

A NEW METHOD FOR SIMULATING CONTACT FORCE BASED ON STATIC STRAIN EQUIVALENCE HYPOTHESIS
Journal of Sound and Vibration, 2002Abstract In this paper, a strain-based contact force simulation method (abbreviated as strain-based method or stain method) for low-velocity impact is proposed on the basis of static strain equivalence hypothesis, in which a straine at the contact point of a structure is selected as a quantity to evaluate the contact force.
