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.

CONTACT and BETA CAE Systems Launch a Development Partnership

CONTACT Software and BETA CAE Systems have launched a development partnership to incorporate the field of product validation into Product Lifecycle Management (PLM). This will enable two leading software manufacturers in their relevant fields to bundle their know-how: CONTACT in PLM and BETA in the field of simulation. The cooperation aims to close the gap which has previously existed between the worlds of CAD and analysis with an integrated range of solutions. This kind of trans-discipline support in PLM context is in particularly high demand among automobile manufacturers and suppliers, as well as other sectors in the manufacturing industry, to speed up the development process and improve the traceability of verification results.
