Digimat-FE to identify Anisotropic Damping Behavior of multi-phases materials

Challenge:

Reinforced plastics and composite materials are chosen more and more because of their improved performance regarding damping for NVH applications compared to current metals. Material specialists need to efficiently identify this mechanical characteristic which, like the stiffness and failure, is anisotropic and driven by local fiber orientations in the material’s microstructure. Moreover for NVH purposes, the frequency dependency must be clearly identified in order to provide accurate material models to design engineers.

Benefits:
  • Available in < 2 days when using available constituent models
  • Quickly evaluate various multiphase materials to identify the best candidates for NVH targets
  • Avoid waiting time and unneeded cost of performing additional experimental tests for each candidate material

Effect of Residual Stresses Induced by Manufacturing Process in Discontinuous Fiber Composites (DFC) Made Part

Challenge:

Discontinuous fiber composites (DFC) are produced by compression molding of prepreg chips which are made of a combination of unidirectional fiber and a Thermoset or ThermoPlastic matrix. In some cases, matrix is made of thermoset which consolidate through a chemical/ cure reaction at elevated temperature. However, when the curing cycle is not well monitored it can be observed some cracks that appear between the chips due to apparition of thermal stresses normal to two chips.

Due to their complex microstructure, these materials request the definition of new dedicated methods in order to capture accurately the local orientation and to compute the local homogenized properties in order to simulate correctly the curing and the design process. Hence, the Digimat platform is used to build a complete methodology to compute these residual stresses and to take them into account during the design cycle of the part.

Benefits:
  • Propose a complete methodology to analyze Discontinuous Fiber Composites: Understand the effect of the local microstructure on the behavior of the part.
  • Improve the understanding of the effects of the manufacturing cycle parameters: Evaluate the risk fo the apparition of defects between the chips for a given set of parameters of manufacturing (pressure, temperature histories). Though their nature is different, this procedure can be applied for both, thermoset or thermoplastic resin.

Digimat Virtual Allowables

Challenge:

Designing lightweight CFRP structures with confidence requires access to allowables values. Allowables generation is extremely time and money consuming. Various layups, coupon tests and environment conditions must be covered for each characterized material system. Each test configuration must be repeated many times to obtain a statistical evaluation of the mechanical property.

Results Validation:

Digimat-VA successfully predicted allowable values within 10% error for all cases except the soft open-hole tension scenario. Typical run times for unnotched tests were 3 minutes, while it look less than 10 minutes for open-hole cases.

Use of Digimat to Simulate Progressive Failure in a T-Stiffener Accounting Voids Due to Manufacturing Defects

Challenge:

Laminate T-stiffeners are widely used in the aerospace industry to transfer the 3D complex loads between the stiffeners and the skins. However, the way they are manufactured can affect the inherent properties.

In this case, we have considered that the stiffener and the skin were assembled using an RTM process but because of the poor infiltration of the resin due to the fiber orientation changings, some dry spots appear in the noodle. These dry spots or voids affect the mechanical properties of the noodle and this knock-down of properties must be taken into account during the design process.

Results Validation:

With Digimat, effective modeling solution enables to understand the sequence of failure of the structure and the resultant load level. The results allowed to capture the progressive loss of stiffness of the structure and the resulting load.

Simufact Reduces Development Costs and Time in Cold Forming Tool Design

Overview:

Omni-Lite Industries is an advanced materials company. They recently designed a new part that was exhibiting a unique material flow. The part was cold formed out of 1100 aluminum material. The manufacturing process for this new part utilized a three-die progression, and was produced on a Nakashimada TH3-6A cold forming machine.

Results Validation:

Omni-Lite found that there is a very accurate correlation between the software prediction of material flow and the real-world results from the heading tooling. The results prove that simulation is a very necessary tool to use for cold forming tool design in order to reduce development cost and product development lead time.

Benefits:
  • Reduce product development costs
  • Reduce time to market by eliminating need for repetitive physical testing
  • Very close correlation between physical test results and Simufact simulation results
