Composites, plastics. CompMechLab Experience

CompMechLab research engineers have been providing services in the area of composite materials numerical and analytical multi-level simulation and analysis for more than 25 years. CompMechLab has successful experience of simulating almost all stages of composite materials and structures lifecycle: manufacturing, strength, buckling, fracture and failure. Numerous projects have been done by requests of world leading industrial companies (Airbus, Boeing, Ahlstrom):

• Code development and application for simulation of resin transfer molding and thermoset curing during manufacturing of laminates;

• Development and application of multi-level homogenization for unidirectional ply with periodic and chaotic fiber patterns;
• Development and application of multi-level heterogenization for determination of micro-stresses in the local zones of stress concentration, load application, contact interaction;
• Finite element simulation of free edge effects in laminates, computation and analysis of singular stresses, optimization of composite plies stacking;
• Finite element simulation of delamination;
• Finite element prediction of damage accumulation and fracture propagation in laminates and UD plies;
• Development and application of algorithms for cracks propagation simulation with adaptive remeshing;

• Finite element simulation of linear and dynamical non-linear buckling, analysis of energy-absorbing properties of honeycomb laminates;

• Finite element modeling of strength and failure of glass- and carbon-fiber non-crimp fabric composites

• Finite element simulation of statics, dynamics, strength and failure of composite constructions.
