PhD: Cohesive Zone Modelling for Crack Growth in Composites

DTU Wind Risø 101; Roskilde; On-site; DKK 420,000 - 540,000; Full time

Job summary

DTU Wind and Energy Systems at the Risø Campus, Roskilde, invites applications for a PhD position focused on fracture mechanics of composites and cohesive zone modelling. The project combines finite element simulations with experimental validation to study crack growth in long-fibre reinforced materials.

The successful candidate will have a two-year master's degree or equivalent and a strong background in solid mechanics, FEM, and composites, with experience in programming and materials testing

Qualifications

• Theoretical background in solid mechanics
• Proficiency in FEM modelling
• Theoretical background in composite materials based on long fibres

Responsibilities

• Development and implementation of mixed mode traction-separation laws into cohesive zone models in finite element software (ABAQUS)
• Fracture mechanics testing of medium-size specimens in the laboratory
• Compare prediction from the cohesive zone model with experimental data from crack growth in medium-size specimens
• Microscale investigation of damage using AE, SEM and X-ray tomography
• Co-supervise BSc and MSc student projects in the area
