Structural analyses

In the area of structural analyses, we calculate stress states and deformations of mechanical components and their assemblies. Based on the structural evaluation, we can confirm compliance with requirements applicable to the component or we can propose structure modification to satisfy those requirements. We also often evaluate lifetime of cyclically loaded components with respect to the material fatigue. We can propose better material utilization within the structure to increase the service life and reliability of the machinery or to reduce the product cost.

We perform structural analyses of simple frames, complicated parts as well as of complex assemblies accounting for frictional contacts and other types of nonlinearities. We are also able to make numerical simulations using special constitutive material models (anisotropic, orthotropic, hyperelastic, creep). We also deal with fracture mechanics and stability analyses.

Structural analyses may include the following tasks:

-      Static calculations including different types of nonlinearities (geometrical, material, contact)

-      Design of part shapes or structure configurations to satisfy requirements on the weight, cost, service time, stiffness…

-      Lifetime calculations (high and low cycle fatigue)

-      Strength calculations of composite parts

-      Assessment of thin-walled structure stability (linear and nonlinear buckling)

-      Modeling of the crack propagation and calculation of the remaining life of a component

-      Optimization (weight reduction, increasing service life, natural frequency optimization, cost reduction…)

-      Comparison of different designs (different concepts, manufacturing technologies, materials…)    


- Time savings

  - We can help you to meet the schedule

  - Identification of potential issues during the design phase (elimination of operational problems and warranty claims)

- Cost savings

 - Elimination of necessity to build a prototype (product behavior can be tested using numerical models)

 - Lowering of operational failure risk and thus reduction of costs related to solving the failures

- Competitive advantages

 - High quality engineering analyses reduce the potential of products to fail (faulty product harms the reputation of the manufacturer)

 - Our technical report can help you to demonstrate to your customer compliance with the requirements on the product
