Phase field modeling of corrosion damage

Publikováno v: Corrosion Reviews. 40:343-354

A phase field (PF) based electrochemical model is presented for simulation of galvanic corrosion. Distributions of electrolyte potential and current density on anode and cathode surfaces are obtained by coupling the PF variable with electrochemistry.

A Thermodynamic Entropy Approach to Reliability Assessment with Applications to Corrosion Fatigue

Autor: Anahita Imanian, Mohammad Modarres

Publikováno v: Entropy, Vol 17, Iss 10, Pp 6995-7020 (2015)

This paper outlines a science-based explanation of damage and reliability of critical components and structures within the second law of thermodynamics. The approach relies on the fundamentals of irreversible thermodynamics, specifically the concept

Data-Driven Sensitivity Analysis for Static Mechanical Properties of Additively Manufactured Ti–6Al–4V

Autor: Evan Diewald, Antriksh Sharma, Jack Beuth, Anahita Imanian, Yongming Liu, Jie Chen

Publikováno v: ASCE-ASME J Risk and Uncert in Engrg Sys Part B Mech Engrg. 8

Additive manufacturing (AM) has been extensively investigated in recent years to explore its application in a wide range of engineering functionalities, such as mechanical, acoustic, thermal, and electrical properties. A data-driven approach is propo

A thermodynamic entropy-based damage assessment with applications to prognostics and health management

Autor: Anahita Imanian, Mohammad Modarres

Publikováno v: Structural Health Monitoring. 17:240-254

To advance the traditional structural integrity and life estimation approach, this article presents an explanation of damage and develops an alternative approach to damage assessment based on the fundamental laws of thermodynamics. This explanation p

Phase-Field Models for Fatigue Crack Growth

Autor: Anahita Imanian, Alain Karma, Ataollah Mesgarnejad

We introduce a class of models based on near crack tip degradation of materials that can account for fracture growth under cyclic loads below the Griffith threshold. We incorporate the gradual degradation due to a cyclic load through a flow equation

Thermodynamics as a fundamental science of reliability

Autor: Anahita Imanian, Mohammad Modarres

Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability. 230:598-608

Cumulative hazard and cumulative damage are important models for reliability and structural integrity assessment. This article reviews a previously developed thermodynamic entropy–based damage model and derives and demonstrates an equivalent reliab

Piecewise stochastic rainflow counting for probabilistic linear and nonlinear damage accumulation considering loading and material uncertainties

Autor: Nagaraja Iyyer, Haoyang Wei, Jie Chen, Yongming Liu, Anahita Imanian

Publikováno v: International Journal of Fatigue. 140:105842

A new framework is proposed for probabilistic fatigue life prediction considering randomness from both loadings and material properties. Piecewise stochastic rainflow counting (PSRC) is proposed to transform random loading spectrums to block loadings
