  • 3D full field deformation measurement using digital image correlation 
    Lowhikan, SS; Mallikarachchi, HMYC [Conference-Abstract]
    3D deformation and strain are crucial parameters in engineering design and construction. Precise 3D full-field measurement is useful in identifying the response of the structure under a given loading condition. Digital ...
  • Analysing the non-linear bending behaviour of ultra-thin woven composites at high curvatures 
    Tennakoon, TMH; Mallikarachchi, HMYC [Conference-Abstract]
    Deep space missions require self-deployable structures built of ultra-thin materials which can be carried to space in a limited space. Therefore, a growing demand for ultra-thin woven composites has been identified in ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Out-of-plane deformation measurements using digital image correlation 
    Gamage, VGES; Mallikarachchi, HMYC [Conference-Abstract]
    Accurate measurement of 3D full-field deformation is paramount for the development of modern applications in structural engineering. Over the past decade, digital image correlation commonly referred to as DIC has emerged ...
  • Pressures exerted on silo walls due to infill bulk material discharge 
    Dissanayake, TD; Mallikarachchi, HMYC [Conference-Abstract]
    Silos are one of the most common containment structures used in industrial applications worldwide for the storage and handling of bulk granular materials such as grains, cement, coal, fertilizers, minerals, chemicals, ...
  • Structural analysis of ancient stupa in Sri Lanka 
    Premarathne, SGIM; Mallikarachchi, HMYC [Conference-Abstract]
    Ancient stupas in Sri Lanka hold immense historical, archaeological, and religious significance. These monumental structures, dating back to ancient times, serve as tangible links to the country's rich cultural heritage. ...
