About k2 E+C
k2 E+C GmbH engineering consulting is an engineering office based in Hamburg that has been working as calculation engineers for more than 25 years. The company performs linear and nonlinear FEM analyses, analytical structural calculations, strength, stability and fatigue verifications as well as optimizations. Services include fatigue strength calculations using an internally developed tool, numerically supported buckling safety analyses (GMNIA), FEM analyses of offshore grout connections, analytical verifications for wind turbines (Eurocode 3, IEC, DIBt), drivetrain verifications, and dynamic FEM analyses such as response spectrum analyses and modal analyses. For calculations, simulation and visualization, FEM software such as ANSYS in the latest version is used. Key industries are wind energy, offshore, shipbuilding, aircraft construction, steel construction as well as mechanical and plant engineering and automotive engineering. The company also supports certification as well as test definition, test supervision and evaluation, and delivers results as a short presentation or a verification-ready report.
