Stress Engineer - Non-linear & Propellants

pThe 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. /p pA core part of this role is the structural simulation of propellant grains, liner bonds, thermal protection systems (TPS), and propellant-liner-casing interfaces - combining FEA with material characterization and test correlation to build substantiated models of energetic material assemblies. /p h3What You'll Do /h3 ul liConduct stress analysis using both classical hand-calculation methods and FEA - linear and non-linear, static and dynamic /li liSimulate 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 /li liConduct non-linear simulations covering geometric non-linearity, material non-linearity (plasticity, hyperelasticity for propellant and elastomeric materials), and contact mechanics /li liPerform thermomechanical analysis across metallic, composite, bonded, and polymeric structures under thermal cycling and operational loads /li liSupport experimental characterisation of propellant, liner, and bonded joint materials; feed test results (lap shear, peel, tensile, and DMA data) into material models and allowables /li liCorrelate FE predictions against strain gauge, load, and thermal test data; validate and update models accordingly /li liPrepare stress reports, margin-of-safety calculations, and design justification documentation /li /ul h3Requirements /h3 h3What You'll Need /h3 ul liMaster's degree in Aerospace Engineering, Mechanical Engineering, or a related field /li li3-5 years of industry experience in stress analysis of aerospace or mechanical structures /li liProficiency with FEA packages: NASTRAN (Femap or equivalent), Abaqus, or Optistruct/HyperWorks for both linear and non-linear analysis /li liStrong classical stress analysis skills: beam theory, buckling, fastener and joint analysis, margin-of-safety calculations /li liExperience with non-linear material modelling - plasticity, hyperelasticity, or viscoelasticity; familiarity with propellant or elastomeric material constitutive models is a strong advantage /li liExperience with thermomechanical or thermal-structural analysis /li liExperience correlating FE predictions with experimental test data /li liBackground in solid rocket motor, propulsion, or energetic structures is a strong advantage /li liFluent in English; German or French is an advantage /li /ul #J-18808-Ljbffr
