CAX/EDA admin 0评论
MSC Marc 2013.0.0
  软件公司日前宣布发布新版Marc 2013。 2013的新功能可帮助工程师们轻松、高效地对产品的高度非线性行为进行仿真,从而改进产品质量。 2013增强了易用性,减少了用户的建模工作量,同时为公司节省了时间,有望于五月发布。
 新的接触分析能力,准确、易用在该版本中进一步增强了 Marc 在业内领先的接触分析能力。

对石油天然气、汽车、航空航天及生物医学行业的众多工程应用中遇到的套管或者筒中梁结构可轻松地进行建模和分析。Marc 2013 简化了套管以及任何常规横截面梁单元的三维自动扩展,可在套管与梁或者其他刚性或可变形单元接触过程中捕获其变形。

在原有过盈配合功能基础上,能更加简便、灵活地实现组件中的过盈配合设置,尤其是大过盈量或不均匀分布的过盈配合,节约了建模时间并提高了计算精度。

片段对片段的接触分析支持多物理场仿真,可帮助获得更加光顺的云图结果,提高在汽车、航空航天、能源及制造行业应用中的求解精度。

新的材料模型进一步提高精度

随着弹性体材料应用的快速增长,了解其完整的非线性特性和损坏累积具有重要意义。

采用全新的 Bergström-Boyce 模型,可精确地仿真超弹性材料随时间变化的大应变粘弹性特性。可结合损伤模型来表征在弹性体中的永久变形,从而提高精度并帮助用户更好地设计轮胎、密封件及弹性体轴承等弹性材料产品。

弹性体材料由于其阻尼特性广泛应用于经受动态激励的产品中。

可通过谐波分析中的粘弹性材料特性来计算与频率有关的刚性和阻尼特性,并用来支持 Marc 中所采用的线弹性和超弹性实体模型。还可规定这些材料的热流变特性,以及包括随温度变化的储存和损耗模量。

高级断裂力学分析能力

新型连续体损伤模型可仿真三级损伤的演变,即孔隙生成、长大及聚结。它使用 Gurson-Tvergaard-Needleman 公式扩展了当前的损伤建模能力,并采用更少的物理参数来表征损伤的演变。该功能可帮助工程师们更加精确地识别板料成形、冲压等制造过程中的损伤累积及潜在失效。

裂纹扩展分析中的一些功能增强包括三维实体模型中的裂纹扩展,更好的局部细化功能、全局网格重划分能力,可在裂纹尖端处实现更精细的网格划分。可方便地将裂纹尖端置于结构中的任意位置,减少建模工作量,并能使用户更快捷、更准确地进行裂纹萌生和裂纹扩展的研究。

可提高生产率的全新解决方案

在该版本中,Marc 的制造过程分析能力进一步增强,改进了对多级成型分析更好的支持。

新功能以极其简单的方式支持多级成形过程的链式分析。用户可方便地将内部变量从一个仿真模型转递到下一个仿真模型中,并可更新接触体,如模具等。还可重复使用之前的结果,以便保留上一次分析过程中或结束时的模型状态,而无需大量的重启动文件,这样可提高灵活性,同时降低了对计算机资源的需求。

新型多物理场分析能力实现了结构与磁感应热的耦合分析。借助这一方法,精密制造工程师能够确定相应参数,从而控制受感应加热影响的板材、喷气桨叶或者其他工件的热量。

MSC Marc 2013.0.0 | 1.4 Gb

MSC Software Corporation, the leader in multidiscipline simulation solutions that accelerate product innovation, announced the new release of Marc 2013. The new capabilities of Marc help engineers improve product quality by simulating highly nonlinear behavior of their products efficiently and easily. Ease of use enhancements reduces user effort in model creation and saves time for companies.

Release highlights:

New Contact Analysis Capabilities for Ease of Use and Accuracy.

The industry leading contact analysis capabilities in Marc have been improved further in this release.

- The tube-in-tube or beam-in-tube behavior encountered in many engineering applications in oil and gas, automotive, aerospace and biomedical industries can be modeled and analyzed with ease. Marc 2013 facilitates automatic expansion of pipe and any general cross-section beam elements to capture their behavior during contact with beams or other rigid and deformable elements.
- Interference fit, commonly encountered in assemblies, is also made much easier and more flexible, saving time and improving accuracy.
- The expansion of segment-to-segment contact support to multiphysics provides smoother contours, and improved accuracy in several applications in automotive, aerospace, energy, and manufacturing applications.

New Material Models Improve Accuracy

With the rapid growth in the usage of elastomers, it is important to understand their complete nonlinear behavior and damage accumulation.

- The new Bergström-Boyce model may be used to accurately simulate the time-dependent large strain viscoelastic behavior of hyperelastic materials. It may be combined with damage models to represent the permanent set of the material that is often observed in elastomers, which improves accuracy and helps users create better designs of elastomeric products like tires, seals, and elastomeric bearings.

Elastomers are heavily used in products that experience dynamic excitations due to their damping characteristics.

- Viscoelastic material properties in a harmonic analysis may be used to compute the stiffness and damping properties as a function of frequency, and is supported for linear elastic and hyperelastic material models available in Marc. Thermo-rheologically-simple behavior of these materials can also be specified to include temperature dependence of storage and loss moduli.

Advanced Failure Analysis Capabilities

A new Continuum Damage Model simulates the three stages of damage evolution, namely void generation, growth and coalescence. It expands the current damage modeling capability using Gurson-Tvergaard-Needleman formulation, and uses fewer physical parameters to represent damage evolution. This capability helps engineers to more accurately identify damage accumulation and possible failure in manufacturing processes like sheet forming and stamping operations.

Several enhancements in crack propagation studies include general crack propagation in 3-D solids, and better locally refined, automatic global remeshing capability to provide finer mesh at crack tip. Easy placement of crack tip surfaces in an arbitrary location, without concerning about splitting element faces reduces modeling effort and enables users to perform crack initiation and propagation studies faster, and more accurately.

New Solution Schemes for Higher Productivity

Marc's manufacturing process analysis capabilities have been further enhanced in this release with improved support for multistage forming.

- The new capability supports simulation of chained analysis for multi-stage forming processes in a very easy manner. Users can move the internal variables from one simulation to the next easily and update the contact tools/dies. Prior results can also be re-used so that the state of the model from the previous analysis is retained, without the need for large restart files, leading to more flexibility and reduced computer resources requirements.
- New multi-physics capability enables coupling of structural analysis with a magnetodynamic-thermal analysis. Using this methodology, precision manufacturing engineers can determine the parameters to control the heat of a sheet, jet blade, or other work-piece induced by induction heating.
