The accomplishment of FE calculations, consulting services and projects in the field of material data identification and experimental mechanics is calculated according to industry standard hourly or daily rates. We will gladly prepare a custom quote upon request. A small consulting project might look like this:
Example 1: Consulting Project (ca 3 days)
In many cases, the situation in the computation units is such that although the staff and the right software for the implementation of FE-simulations exist, but again and again you encounter problems in the form of low accuracy or validity of the results. It is often only small, but crucial steps that can lead to a significant and sustained quality improvement.
In discussions with users of FE-software we may quickly identify deficiencies or structural problems in data management among the different departments involved in the development of components. Often our customers have a large amount of experimental data, which has not been fully evaluated yet. With our help much better material data for FE simulation can be determined from these experimental data at reasonable costs.
The added value due to a better application of FE-simulation tools and the optimal utilization of existing experimental data is usually a multiple of the costs.
Example 2: Determination of material data for nonlinear material models (ca 7-10 days)
In most cases, you can only simulate the behavior of a component by using a nonlinear material model. The normally available material data is insufficient to achieve a meaningful simulation result, especially at high material stress.
- Material laws for metals must include the plastic behavior until failure whereas usually Hardening parameters are taken into account. For plastics also the time-dependence of the material behavior plays an important role. Finally there are also many damage effects in the material which have to be included in the mathematical formulations.
- In most cases the input data for a FE simulation cannot be determined using simple tension tests. To simulate components later, multiaxial stress-strain states have to be taken into account experimentally and within the identifiaction process of the material parameters.
After the identification of material parameters with our procedures, our customers can continue their development of components, including the topology optimization, without further testing on prototypes. This allows for example the omission of iteration steps and many experiments during the development process of a component. The cost reduction potential is often tens of thousands of euros.
To give you a better idea of the average size and the typical contents of a project in the field of "Determination of material data for the FEM", we have put together the following example:
Determination of material data from tensile tests on perforated and notched specimens (10 specimen)
- Test preparation: Sample preparation, preliminary tests, preliminary discussion with the customer
- Experimental procedure: Tensile tests on perforated and notched rectangular specimens, measurement of the force response and optical detection of load-dependent displacement fields on the specimen surface
- Data analysis: Identification of inhomogeneous displacement fields, interpolation of the measured with the FEM-simulated displacement fields, material data validation on single tests, determination of definitive material data sets with regard to all conducted tests, selection of the optimum material model
- Final Report: Careful preparation and description of results and provision of material data sets for the FEM, final discussion with the customer
All project examples can be individually adapted to the needs of our customers. There are versatile possibilities of project design, always with the aim of achieving an optimal result regarding quality and economic benefit for our customers.
