Digimat
非線性、多尺度的材料與結(jié)構(gòu)建模平臺(tái)
Digimat 使工程師們能夠?qū)?fù)合材料進(jìn)行微觀和宏觀分析,預(yù)測(cè)其表現(xiàn)并計(jì)算其機(jī)械、熱及電氣特性,以供各種類型的下游故障影響分析使用。
對(duì)于模制材料而言,工程師們通常通過(guò)收集材料信息來(lái)開始建模,并結(jié)合來(lái)自 Moldflow、3D-Sigma、Moldex3D、Simpoe 或其他注模仿真解決方案的定向數(shù)據(jù)。Digimat-MAP 可計(jì)算來(lái)自注模網(wǎng)格的殘余應(yīng)力及溫度,并定義理想結(jié)構(gòu)的故障影響分析網(wǎng)格。因此,許多用戶直接采用 FEA——例如 MSC Nastran 和 Marc,以及其他有直接接口的解算器。他們也可以使用 Digimat 的 MF、 MX、FE 模塊來(lái)查看復(fù)合材料及其組分的試驗(yàn)數(shù)據(jù),并評(píng)定有希望的候選材料。在制造期間,用戶可查看部件幾何形狀、材料流之間的緊密聯(lián)系、所生成的纖維定向以及所有這些對(duì)部件最終機(jī)械行為的影響。

Digimat-HC
![]() | Digimat-HC是一款用于夾層板的彎曲及平面剪切試驗(yàn)的多尺度建模工具。它是簡(jiǎn)便全面、精確靈活的軟件工具。 |
Digimat-AM
![]() | Digimat Additive Manufacturing (AM) is a holistic simulation chain for AM, providing the unique combination of material engineering, process simulation and structural engineering to bring AM efficiency and performance to the next level. By applying multi-scale material modeling techniques to AM of polymers (unfilled and reinforced), Digimat virtual material compounding and characterization is a key enabler to developing new materials. Users can significantly reduce physical tests, understand key parameters driving the material behavior and easily create new material systems such as lightweight lattices, opening the door to even more innovative designs. For Additive Manufacturing to make a successful transition to a standard production technique, dedicated design and engineering tools are required. By enabling as-manufactured part performance predictions – and therefore design optimization, integrative simulation such as proposed by e-Xstream is certainly a must. By accounting for the printing direction and the effects of defects, customers are now able to perform accurate structural analyzes and bring more confidence in the design validation of Plastic and Composite parts. |
Digimat-RP
![]() | Digimat-RP (Reinforced Plastics) is an easy and efficient solution for the design of fiber reinforced plastic parts. It provides engineers with a guided workflow tool that aids in the setup and streamlines the process of accurate analysis of plastic parts in a robust, fast and easy manner. It bridges the gap between injection molding and nonlinear FEA of plastic parts. Digimat 5.0.1 supports the setup of 3D analyses with Marc, Nastran, Abaqus, Ansys, and LS-Dyna based on Moldflow, Moldex3D, Sigmasoft or Timon 3D processing results. All Digimat solution technologies are supported. Jobs can either be run and monitored on a local computer or packaged for the remote solution on a cluster. Digimat-RP is an intuitive 3-step process that enables a part engineer (not necessarily a material expert) to do predictive analysis of plastic parts using one single process oriented product (RP) instead of the original four. RP is easy to learn and to use by “non-experts”. The experts can continue to use the general-purpose building blocks and prepare the models for easy use in RP. Key benefits:

Digimat-VA
![]() | Digimat-VA (“Virtual Allowables”) is an efficient solution that empowers engineers to virtually compare materials before going into the lengthy physical allowables. By generating virtual allowables, engineers can now start the component design in parallel to the physical allowable campaign. Digimat-VA is a vertical solution is developed to compute, instead of test, the behavior of composite coupons (unotched, open hole, filled hole, ...) to screen, select and compute the allowables of composite materials.
