Do you need support with the design of your components or production tools? Then FemStas is the right place for you! With a broad portfolio in the field of computer-aided calculations, we help you, for example, to bring your products to market faster and to reduce development costs. In addition, the integration of simulations into your development process results in the following advantages for you:

  • Even at an early stage of development, knowledge can be gained about later component properties. This makes it possible to optimize your component at a time when design changes are still possible with little financial effort.
  • The evaluation of different design variants can be carried out without extensive test series.
  • Through the targeted use of simulations, you will build an improved understanding of components.

The following are the key areas of focus for FemStas in the Services business area. If your specific application is not included, just contact us! In a free initial consultation, you have the opportunity to get to know us personally and talk about your application.

  • Static Analyses

    Static structural mechanics is the most commonly used and therefore the most widespread type of analysis. It enables simulations of components that are subjected to further loads in addition to their own weight, such as internal or external forces, pressure or acceleration. By evaluating deformations, strains and mechanical stresses, failure points can be identified at an early stage of the development process and thus prevented without costly prototype testing. In addition, static FEM analyses can prevent the oversizing of components, which leads directly to material savings.

  • Dynamic Analyses

    If loads occur at high speeds, the inertias of the bodies have a decisive influence on the loads on the components and must be taken into account in the simulation. This is particularly the case with shock and impact loads or with rapidly rotating components.

    Possible fields of application

    • Mechanical Engineering
    • Automotive
    • Drive Technology
    • Rotors

    Your advantages

    • Realistic consideration of deformations, stresses and strains at high speeds
    • Transient consideration of the load history
    • Basis for lifetime calculations

  • Fatigue

    In many cases, cyclic loads occur, which lead to fatigue of the material. For the failure of a component, it is then not the statically tolerable loads that are relevant, but the number of oscillations at the defined load level. Wöhler curves describe the relationship between the stress amplitude and the number of cycles and form the basis for fatigue strength verifications.

  • Fluid Simulations

    Flow simulation, also known as computational fluid dynamics (CFD), is used for the realistic calculation and representation of flow-relevant processes. Decisive factors are viscosity of the flowing medium, temperature, pressure and velocity.

    Measurements of flow processes are often only possible with considerable effort or not at all. Here FemStas supports you with CFD simulations.

    • Pressure loss investigations
    • Simulate flow for cooling
    • Flow processes of melts

  • Noise

    Unwanted noise is a common problem that occurs only during use and is difficult to reconstruct with experiments. With a simulation of the sound properties of your component, statements about sound conduction, absorption or sound radiation can be made at an early stage.

    Possible fields of application

    • Mechanical Engineering
    • Automotive
    • Offshore
    • Plant engineering and construction
    • Noise insulation

    Your advantages

    • Reduction of noise emissions
    • Compliance with emission guidelines
    • Reduction of component and prototype tests
  • Thermal Analyses

    A thermal analysis can be used, among other things, to make statements about the temperature field that occurs during operation and the corresponding thermal load on your component. For a reliable analysis, heat conduction, convection, thermal radiation or a combination of the mentioned heat transfer types must be considered in the simulation, depending on the application.

  • Modal Analyses
  • Structural Optimization

    Do you want to achieve the maximum stiffness of your components with the least amount of material? Or find out which component dimensions are required to avoid stress peaks, for example?

    One aid here is topology optimization, a calculation method that can be used to determine the optimum component design taking into account the given boundary conditions (loads and restraints).

    FemStas is looking forward to support you in the structural optimization of your components or production tools. Just contact us!

  • Anisotropic Materials

    For a realistic FEM simulation, the description of the material behavior is of crucial importance. For example, when calculating components with anisotropic material properties, it is essential to consider the direction-dependent properties.

    Anisotropic properties can be caused, for example, by inhomogeneities in the material (pores, air pockets, etc.). Manufacturing processes, such as 3D printing, can also lead to direction-dependent material behavior. Furthermore, a typical application for anisotropy can be found in fiber-reinforced materials.

    FemStas supports you both in the measurement of the anisotropic properties of your materials and in the development of suitable material models to describe the determined anisotropic material properties. Just contact us!
