I korthet

This Master's thesis project focuses on material modeling of Carbon Fiber Reinforced Polymers (CFRP) for low-velocity impact simulations using Ansys LS-DYNA. The role involves theoretical and numerical work to develop a structured methodology for predicting damage and failure, with opportunities to collaborate with experienced engineers at Saab Dynamics in Sweden. This is an internship suitable for master's students in relevant engineering fields, commencing in spring 2027.

Ansvarsområden

  • Develop a structured methodology for material modelling of CFRP under low-velocity impact loading in Ansys LS-DYNA.
  • Investigate and compare available composite material models in Ansys LS-DYNA, assessing their theoretical assumptions, capabilities, and limitations.
  • Define material data requirements, including parameters obtainable from standard tests, inverse calibration, and literature sources.
  • Propose and set up a representative low-velocity impact validation case, such as a numerical drop-weight impact test.
  • Investigate relevant modelling aspects including element formulations, damage and delamination modelling, and contact definitions.
  • Evaluate selected material models based on damage representation, data requirements, calibration effort, numerical robustness, and computational cost.
  • Utilize Ansys Discovery, Ansys Mechanical, LS-PrePost, and scripting in Python or MATLAB for pre-processing, model preparation, and post-processing.
  • Provide practical recommendations for model selection, material characterization, parameter calibration, and future validation work.

Krav

  • Master's student in Mechanical Engineering, Engineering Physics, Applied Mechanics, Materials Engineering, or a similar program, nearing completion.
  • Availability to start thesis work in Spring 2027.
  • Interest in composite materials, material modelling, finite element analysis, and structural mechanics.
  • Ability to work independently with theoretical material, technical documentation, numerical models, and simulation results.
  • Analytical and systematic approach to comparing material models and defining a traceable calibration methodology.
  • Pass a security vetting based on current regulations.

Önskade kvalifikationer

  • Previous experience with the finite element method or composite mechanics is beneficial, but not mandatory.
  • Experience or interest in experimental mechanics and material testing.
  • Experience or interest in Ansys LS-DYNA or similar explicit finite element solvers.
  • Experience or interest in numerical optimization and parameter identification.
  • Experience or interest in Python or MATLAB scripting.

Förmåner

  • Opportunity to apply theoretical knowledge to real-world challenges.
  • Collaborate with experienced engineers and specialists.
  • Gain invaluable practical experience.
  • Make a tangible contribution to company growth and development.
  • Potential to be the spark for technological breakthroughs.
