Stress Engineer - Non-linear & Propellants

About the role

The Destinus engineering team is seeking a Stress Engineer to support structural sizing and simulation with a focus on non-linear and thermomechanical analysis of solid rocket motor structures. This role involves structural simulation of propellant grains, liner bonds, thermal protection systems, and propellant-liner-casing interfaces by combining FEA with material characterization and test correlation.

Responsibilities

• Conduct stress analysis using both classical hand-calculation methods and FEA – linear and non-linear, static and dynamic
• Simulate solid rocket motor structures: propellant grain stress and strain fields, bond integrity at propellant–liner and liner–casing interfaces, TPS thermomechanical response, and igniter/nozzle attachment loads
• Conduct non-linear simulations covering geometric non-linearity, material non-linearity, and contact mechanics
• Perform thermomechanical analysis across metallic, composite, bonded, and polymeric structures under thermal cycling and operational loads
• Support experimental characterisation of propellant, liner, and bonded joint materials and feed test results into material models
• Correlate FE predictions against strain gauge, load, and thermal test data
• Prepare stress reports, margin-of-safety calculations, and design justification documentation
