  • 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 ...
  • Formation of plastic creases in thin polyimide films 
    Dharmadasa, BY; McCallum, MW; Mierunalan, S; Dassanayake, SP; Mallikarachchi, CHMY; Jiménez, FL [Article-Full-text]
    We present a combined experimental and analytical approach to study the formation of creases in tightly folded Kapton polyimide films. In the experiments, we have developed a robust procedure to create creases with repeatable ...
  • Simulation of fold-line stiffness in deployable membranes 
    Dharmadasa, BY [Thesis-Full-text]
    New designs for space structures such as solar sails and star shades are based on architectures that follow folding and packaging ofthin membranes. By leveraging recent advances in origami science, it is possible to design ...
