Internship Title: Continuum Damage Mechanics (CDM) based fatigue initiation prediction model integrated to Abaqus. Brief: Continuum Damage Mechanics (CDM) is a promising analysis methodology for better fatigue life prediction & currently has less maturity within Airbus. Objective to further mature the fatigue initiation prediction models developed previously for uniaxial and multiaxial models including aspects of plasticity and variable loading treatment.
Job Responsibility:
Improve the finite element implementation of the previously developed models with required user inputs to integrate with Abaqus
Adapt CDM models to higher complexity such as multiaxial loading, non-localization phenomenon, complex spectra, plasticity, temperature & humidity effects and analyze the results
Validate the developed methods with PoC specimens and correlate with physical test results
Summary of findings and preparation of report
Requirements:
Sound knowledge of solid mechanics, finite element methods
Basic knowledge on structural fatigue
Ability to derive broad conclusions from research articles
Hands on experience with Abaqus along with experience with creating user subroutines preferably UMAT, USDFLD, UEXTERNALDB
