The Computational Mechanics and Engineering AI (CMAI) research group develops next-generation smart computational engineering solutions that support the digital transformation of the built environment.

We integrate mechanics, physics and data-driven artificial intelligence to study materials, structures and digital systems. Our work aligns with major research funding priorities in engineering, sustainability and digital innovation.

Our research is organised into three main areas:

  • Smart Materials
  • Smart Structures
  • Advanced Building Information Modelling (BIM) and Physics-informed Digital Twins

Smart materials

We develop computational models for advanced materials used in engineering applications.

Our research includes:

  • Micro- and nano-structured materials and composites
  • Electroactive materials
  • Biological and bio-inspired materials
  • Quasicrystals and architected metamaterials

By modelling material behaviour across scales, we support the design of materials with specific mechanical and physical properties. This contributes to the development of more efficient and durable systems in areas such as aerospace and civil engineering.

Smart structures

We study advanced computational modelling methods for structures and meta-structures.

Our work includes:

  • Composite aerospace structures
  • Multiscale finite element methods
  • Design optimisation
  • Uncertainty quantification in engineering systems
  • Structural dynamics and dynamical systems
  • Elastic wave propagation and absorption
  • Topological mechanics

We use simulation and optimisation techniques to analyse structural performance under complex loading and environmental conditions. This research supports improved reliability, efficiency and lifecycle performance in engineering systems.

Advanced BIM and physics-informed digital twins

We investigate physics-informed, data-driven artificial intelligence methods for engineering applications.

Our research includes:

  • Neural networks, symbolic mathematics, robotics and natural language processing
  • Multi-dimensional Building Information Modelling (BIM) data and knowledge processing
  • Large-scale engineering computation, data analytics and optimisation
  • Knowledge-based and AI-supported decision-making methods

By combining physical modelling with artificial intelligence, we develop digital representations of engineering systems that support analysis, monitoring and decision-making across the lifecycle of built assets.
