Advanced Nonlinear Analysis

STKO was built to tackle complex nonlinear analyses, from material plasticity to contact interactions and unstable structural behavior. It’s the perfect choice for researchers and engineers seeking flexibility and full control over their models.

  • Perform highly accurate static and dynamic nonlinear analyses

  • Customize every aspect of material and structural behavior

  • Analyze complex phenomena such as softening, snapping, and localization and more

Structures &
Infrastructure

From civil structures to large-scale infrastructure systems, STKO enables detailed and scalable analyses, ideal for the design and assessment of bridges, dams, high-rise buildings and other complex systems.

With STKO you can:​

  • Model complex geometries and large structures with efficient meshing tools

  • Simulate damage, cracking, and progressive collapse

  • Incorporate multiple effects such as cyclic loads, creep, fatigue, and thermal behavior and much more
