VIPER (VIrtual Ply propERty) is a simulation tool developed within the framework of computational micromechanics by IMDEA Materials to predict ply properties of fiber-reinforced composite materials from the properties and spatial distribution of the different phases and interfaces in the composite. The tool is also able to generate composite microstructures with arbitrary fibre geometries as well as hybrid microstructures hence allowing for in-silico ply property design and optimization.
Moreover, IMDEA Materials Institute has developed other in-house codes for modelling and simulation of thermodinamic properties and phase diagrams as well as mechanical behaviour and damage evolution of engineering materials.
Some examples of the user interface and of works done using VIPER are shown in the images below.
