APPLIED MECHANICS
• Crystal houses facade - str uctural glass/cast glass
Challenges:• Cast bricks with desired structural perfor mance• Clear adhesives with good bonding and transparancy properties
APPLIED MECHANICS
• Computational modelling of degrading and failure processes:Novel/robust FE-techniques (XFEM) for arbitrar y crack propagation (left)and multiple/competing fracture mechanisms in composites (right)
APPLIED MECHANICS
• Computational multi-scale modelling techniques:DEM to FEM modelling of damage in porous micro-str ucture cement (left)adequate computational homogenization schemes for failure analysis (right)
APPLIED MECHANICS
Groups/resear ch t hemes:
• Computational modelling of structures (Jan Rots)• (mechanics-based) Structural design (Rob Nijsse)• Computational mechanics of materials (Bert Sluys)
Relevance for SE and BE students:
• Research portfolio with scientifically challenging and societallyrelevant topics
• Challenging topics for MSc-thesis projects and internships• MSc-projects often linked with PhD-projects• U-BASE can help you to connect and support
