Predicting Hydrocarbon Strain Energy via a Group Equivalent Machine Learning Approach

The Journal of Physical Chemistry A
Strain energy is a fundamental measure of the steric and configurational properties of organic molecules. The ability to estimate strain energy through quantum chemical simulations requires at minimum the knowledge of an initial set of nuclear coordinates.

A Strain Energy-Based Equivalent Layer Method for the Prediction of Critical Collapse Pressure of Flexible Risers

Volume 5: Pipelines, Risers, and Subsea Systems, 2018
Flexible risers are one kind of flexible pipes that transport fluid between subsea facilities and topside structures. This pipe-like structure consists of multiple layers and its innermost carcass layer is designed for external hydrostatic pressure resistance.

Fatigue crack growth in miniature specimens: The equivalence of ∆K-correlation and that based on the change in net-section strain energy density [PDF]

Scripta Materialia, 2016
Abstract In fatigue crack growth experiments of miniature specimens of Ti-6Al-4V alloy, it is shown that the stress intensity factor range (∆K) cannot uniquely correlate the crack growth rates based on the standard stress intensity factor solution, but can only on the basis of the solution for uniformly displaced ends.

Structural Multi-Damage Identification Based on Modal Strain Energy Equivalence Index Method

International Journal of Structural Stability and Dynamics, 2014
In 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.

Fatigue strength of a fork-pin equivalent coupling in terms of the local strain energy density

Materials & Design, 2008
Abstract The fork-pin coupling of the front suspension of a motorbike is very important for the reliability and the safety of the entire vehicle. One of the more important causes of failure of the component is fatigue under fully reversed bending load.

Stress and strain concentration factor evaluation using the equivalent energy concept

Materials Science and Engineering, 1983
Abstract The energy approach to local stress and strain evaluation in a notch in materials with a power law type of hardening curve is generalized. The formulae for relative stress and strain concentration factor evaluation using the generalized equivalent energy method, the Neuber method and the Hardrath-Ohman method are derived and the results are ...
