Our approach
In linear and nonlinear structural analyses, we are dealing with an engineering investigation method that focuses on the behavior of structures and their components under various loads. It aims to analyze the structural properties, responses to external forces, and the effects of loads on the structure.
Software used: MSC Nastran, Marc, Patran, SimDesigner, MSCApex,MSC Fatigue
Linear structural analyses
According to the definition of boundary conditions, the occurring stresses and deformations of the component or assembly are calculated within linear material behavior and deformation.
This includes the following disciplines:
- Statistical analyses
- Buckling calculations
- Thermal (steady-state & transient)
- Thermomechanics
Modal analysis in the form of:
- Normal modes
- Differential Stiffness
- Frequency response (“linear” dynamics)
Nonlinear calculations
Linear and nonlinear dynamic structural analysis in the time domain:
- Real natural frequency calculation
- Harmonic analysis and damping
- Response – Spectrum Analysis
Thermo-mechanically coupled structural analyses:
- Thermal stress and strain calculations
- Temperature dependent elastic material
- Temperature dependent plasticity
Nonlinear structural analyses:
- Nonlinear elastic material behavior (small and large deflections)
- Elasto-plastic material behavior (small and large strains) for isotropic, orthotropic and anisotropic materials.
- Hyperelastic material behavior (elastomers) – relaxation, viscoelasticity, viscoplasticity
Contact analysis (2D and 3D):
- Deformable – Deformable (discrete and analytical)
- Rigid – Deformable
- Contact of several bodies (2D and 3D surface contacts)
Operational strength and fatigue calculations
- Predictions about the service life of components
- Analyses of crack formation and propagation
- proof of strength according to FKM, EC, DIN EN 13001
To adress the tasks described here, we use CAE Fatigue!
Thermal calculations
Calculation of:
- Balancing effects
- transient heat transfers
- Convections
Thermal analyses and thermal-mechanical coupled structural analyses:
- Linear and nonlinear temperature field analysis
- Thermal stress and strain calculations
- Temperature dependent elastic material
- Temperature dependent plasticity
Shape optimization
- Topology optimization for castings and milled parts
- Topography optimization for stiffness optimization of sheet metal parts
- Topometry optimization and sizing for weight optimization under consideration of manufacturing plans
- Optimization of additively manufactured products; both for plastics and metallic materials. This involves optimizing the product as well as the manufacturing process (e.g. optimum alignment in the machine, with regard to support structures and warpage).
