Effect of Defects on Part Made with AFP Using Digimat

Product Marketing — Wed, 27 Feb 2019 23:19:32 +0000

Automatic Fiber Placement (AFP) is a fast and efficient deposition process of carbon prepreg for large component application. To accommodate the composite strips onto a double curved surface, the tows can be cut then restarted and slightly misoriented, yielding to the apparition of gaps between the tows. These two defects, i.e. the gaps and misalignment ...

Multi-scale material modeling for additive manufacturing

Product Marketing — Mon, 01 Aug 2016 07:19:02 +0000

While additive manufacturing of reinforced polymers is appealing and increasingly considered for production of actual parts, major obstacles must be overcome by engineers. Dimensional accuracy of the part must obey to strict tolerances that may not be met due to thermally induced part distortion or poor surface roughness. On the material side, an anisotropic material behavior is brought in by the specific 3D printed layered architecture and oriented reinforcements. This process-induced material behavior make the part mechanical response challenging to predict.

Therefore, Digimat, the material modeling platform, can offer you a solution to overcome your challenges.

Impact on a Stiffener for Lower B-Pillar

Product Marketing — Fri, 24 Jun 2016 17:00:54 +0000

L&L Products is a provider of individual and innovative engineering solutions to the automotive industry and is known for superior engineering through the use of state-of-the-art simulation methods in the product development chain. However, they faced the challenges in moving towards greener technology by replacing classical metal design with composite structures. The purpose of transitioning was to utilize the outstanding performance of composite materials. However, this presented difficulties, mainly with predicting the injection molding process and achieving a high-quality prediction of the impact on a short fiber reinforced stiffener beam.

Finite Element Analysis of a UAV Wing

Product Marketing — Wed, 22 Jun 2016 17:00:38 +0000

AeroVironment’s Global Observer is an unmanned aircraft with the wingspan of a Boeing 767 but less than 10% of the weight designed to provide communications and sensing for flights lasting up to one week at up to 65,000 feet. With a maximum wing loading of only 3.5 pounds per square feet, the wingtip deflects greater than 22 feet at its design limit load.

MSC Nastran was utilized to develop nonlinear stress, structural dynamic and aeroelastic finite element models. The structural dynamics model was correlated to a ground vibration test, both of which had to accommodate the apparent mass of the air, which is atypical. The ultimate test of the nonlinear stress model was correlation with the static wing load test.

Structural Analysis and Model Validation for the James Webb Space Telescope ISIM Structure

Product Marketing — Wed, 15 Jun 2016 17:00:16 +0000

The James Webb Space Telescope is a highly sensitive instrument that is positioned using a precise optical metering support structure. This supporting structure is made from composites to reduce thermal expansion effects while reducing weight. The instrument and structure are subjected to temperatures ranging from ambient during launch to cryogenic temperatures while in orbit. Dynamic and static loads are encountered during launch and in operation respectively.

Materials Lifecycle Management for Product Innovation

Product Marketing — Fri, 27 May 2016 17:01:47 +0000

Manufacturing has become much more complex than it was in the past. New designs are created every day, data flows during engineering processes are becoming huge and the number of engineers working together is growing. These improvements bring some challenges in tracing the data and managing the processes and workflows. A materials lifecycle management (MLM) system is a tool that focuses on capturing and managing data all the way from test data to the consumption of this data by CAE applications. It gives the ability to automate test processes, have complete traceability of all the data in the system, and it gives a very deep client integration. It ensures that engineers are using a consistent source of approved materials derived from traceable integrated processes. Furthermore, it is web-based and very easy to install. MLM eliminates a significant amount of tedious manual data management activities and gives engineers the ability to focus solely on innovations and new product designs.
