Composites
复合材料的建模可结合使用专业材料模型和层材料角度数据。可通过部件的厚度指定不同的材料定义和材料角度,并在材料定义中包含层间失效。
- Material models can simulate intralaminar failure mechanisms (fibre and matrix failure).
- Use of tiebreak contacts or cohesive elements to simulate interlaminar failure (delaminations).
- Layered shell elements for modelling ply layup
- Uniaxial and bidirectional fabric material models
- Detailed output on the different failure modes
Crashworthiness
对于许多汽车公司来说,LS-DYNA 是了解车辆结构等复杂系统变形的工具。LS-DYNA 的接触建模能力及其广泛的材料模型使其非常适合此类分析。LS-DYNA 还包括许多汽车应用的特殊功能,如安全气囊、加速度计和高级连接建模。
