AbstractAn Estonian private engineering office provides numerical simulations to model the behaviour of structures under dynamic loading. The simulations can be applied to design the structures to withstand the loads and/or to assess their safety and reliability under given conditions. The advantage of numerical simulations is their small costs compared to the expensive experimental testing. The company is looking for industrial partners developing demanding structural solutions for high reliability.DetailsAn Estonian private engineering office is providing numerical simulations to model the behaviour of structures under impacts, collisions, non-stationary excitation force, ground accelerations, etc. The simulations can be applied to design the structures to withstand the above-mentioned loads and/or to assess their safety and reliability under given conditions. Large geometrical deformations are simulated including the initiation of material failure and crack propagation.Simulations are based on non-linear finite element method using explicit solution schema. The simulations are capable of modelling material´s behaviour until its failure. Large material deformations are modelled using element size dependent material parameters and failure criteria for crack initiation and propagation. The service is provided by experts (D.Sc) involved in research and development methods to assess ultimate strength and crashworthiness of structures. Innovative Aspects: The technology offers precise modelling of material behaviour under large deformations considering material and geometrical non-linearities. The approach is much cheaper as compared to the physical experiments. The technology allows both global- and local-level optimisation of the structures.
