Research interests

Dr Cirak's research is focused on computational modelling and analysis of light-weight structures originating from a wide range of applications, including structural engineering, aerospace and marine engineering. Specific areas of research emphasis include:

  • advanced discretization methods for integrated design, optimisation and analysis of solids and structural components such as beams, membranes and shells,
  • computational fluid-structure interaction with application to micro-air-vehicle design and insect flight, and
  • mechanical modelling and computational analysis of large-scale structural membranes, such as parachutes and inflatable decelerators for outer-space applications.

In terms of computational methods development two overriding themes throughout his research are:

  • the integration of, traditionally disparate, computational analysis and geometry using immersed and b-spline based finite element discretization techniques,
  • the development of scalable computational methods for simulating challenging engineering problems on high-end parallel computers.

Strategic themes

Energy, transport and urban infrastructure

Current research interests include multiscale shape and topology optimisation for lightweighting and fluid-structure interaction with application to biomimetic energy harvesters.

Manufacturing, design and materials

Current research interests include integrated geometric design (CAD), simulation (FEA) and structural optimisation using subdivision surfaces with application to additive manufacturing.
