  • Analysis of curved crease origami structures 
    Kuruppu, KALH; Mallikarachchi, HMYC [Conference-Abstract]
    Research on origami-based folding patterns has led to major technical developments from nanoscale metamaterial to large-scale deployable space structures. Deployable space structures such as solar sails and reflectors ...
  • Characterising the self-opening behaviour of single creased Kapton polyimide films 
    Navaratnarajah, S; Mallikarachchi, HMYC [Conference-Abstract]
    Use of thin folded membranes for deployable structures is becoming increasingly popular especially in aerospace applications such as a deployable solar arrays, sun shields, and solar sails. The folding and compaction ...
  • Design-informed structural optimisation 
    Amarasinghe, IT; Herath, HMST; Mallikarachchi, HMYC [Conference-Abstract]
    Structural optimisation has become an important tool in the field of Civil Engineering, but there is limited research done on structural optimisation of specific structures and components, especially for large construction ...
  • Estimation of fatigue life of steel masts using finite element modelling 
    Kariyawasam, KKGKD; Mallikarachchi, HMYC [Conference-Full-text]
    Fatigue is an important design consideration for tall steel structures. Accurate prediction of fatigue endurance is essential to design the elements subjected to wind and earthquake induced fatigue. The design guidelines ...
  • Finite element simulation of thin folded membranes 
    Dharmadasa, BY; Mallikarachchi, HMYC [Conference-Abstract]
    Deployable gossamer structures use thin filmed membranes folded into different patterns. Predicting the membrane behaviour and the stress propagation in these structures is complex due to non-linear characteristics at ...
  • Homogenisation of ultra-thin woven fibre composite structures under high curvatures 
    Weerasinghe, WUD; Herath, HMST; Mallikarachchi, HMYC [Conference-Abstract]
    Utilising fibre-based textile structure as the composite reinforcement results in making composite more tailorable and effective for applications where various types of loads are anticipated to be supported by the ...
  • Image based displacement measuring technique for in-plane loading 
    Diluxshan, A; Mallikarachchi, HMYC [Conference-Abstract]
    Displacement/ strain measurement plays a significant role in understanding structural and material behaviour. In the local context, commonly used contact based systems have a major limitation when it comes to measuring ...
  • Influence of relative positioning of tows on mechanical properties of thin woven composites 
    Gowrikanthan, N; Mallikarachchi, HMYC [Conference-Abstract]
    Limited capacity in launch vehicles was overcome by the usage of deployable structures. They allow large structures to be packed into compact configurations. Woven fibre composite laminates eliminate the need of mechanical ...
  • Measuring structural dynamics with smartphones 
    Karannagodage, DCDK; Mallikarachchi, HMYC [Conference-Abstract]
