Dataset on simulated microbond tests using finite element method: Simulation cases about different geometrical influences, material behavior, damage evolution, and element meshes

Abstract

This data article provides an extensive dataset obtained from finite element (FE) simulations of microbond (MB) tests. The simulations cover a wide range of structural effects and artifacts that influence the results of the MB tests. A total of 432 simulations were performed,taking into account the various factors such as blade geometry and position, plastic behaviour of thermoset and thermoplastic droplets, material properties of the fibres, residual stresses, fracture modes at interfaces, and FE mesh sensitivity analysis. Each FE simulation consists of blade reaction force, blade displacement, fibre displacement, fibre strain and various energy metrics such as interface strain energy, total strain energy, damage energy and plastic dissipation energy. For ease of reference, the individual data files are organised in a systematic naming sequence based on the simulation matrices, detailing the specific abbreviations for each file. A user-friendly interface is also provided to read and visualisethe data from the output files in relation to the simulation matrix. For more information on the interpretation and analysis of this data, please refer to a research article entitled “Mutual dependence of experimental and data analysis features in characterization of fibre-matrix interface via microdroplets (R. Dsouza et al., 2023)”.
