Characterizing fracture stress of defective graphene samples using shallow and deep artificial neural networks

Dewapriya, MAN; Rajapakse, RKND; Dias, WPS [Article-Full-text]

Advanced machine learning methods could be useful to obtain novel insights into some challenging nanomechanical problems. In this work, we employed artificial neural networks to predict the fracture stress of defective ...
Creep response of laterally loaded piles in ice and permafrost

Puswewala, UGA; Rajapakse, RKND; Domaschuk, L; Shields, DH [Article-Full-text]

A computationally efficient pile element and a time-incremental finite element code are developed to model laterally loaded piles in ice/permafrost, by modelling the pile as a beam supported on a spring-dashpot system. A ...
Joint slip in steel electric transmission towers

Ungkurapinan, N; Chandrakeerthy, SRDS; Rajapakse, RKND; Yue, SB [Article-Abstract]

Joint slip is the relative displacement of a bolted joint under shear. It is greater in transmission towers as bolt diameters are small, members joined are thin, bearing type joints with a lower clamping force are used, ...
Numerical modelling of cracks in masonry walls due to thermal movements in an overlying slab

Dilrukshi, KGS; Dias, WPS; Rajapakse, RKND [Article-Abstract]

This paper describes a numerical modelling exercise employed to understand the propagation of cracks in masonry walls under a time varying thermal load in an overlying roof slab. A structural thermal coupled non-linear ...
