相变诱导塑性（TRIP）是钢材料行为的重要现象。否则可能会导致工件变形。由于建模和仿真中存在开放性问题，TRIP 是当前研究的一个重要领域。有不同的建模方法。著名的 Leblond 模型在商业程序 SYSTUS (SYSWELD)® 中实施。新的实验和研究表明，TRIP 和经典可塑性之间存在交互作用，而 Leblond 模型无法描述这种交互作用。在这篇文章中，我们将 Leblond 模型与另一种方法进行了比较，讨论了优点和缺点。此外，我们还展示了一些 3D 设置中的首次比较模拟。
Transformation‐induced plasticity (TRIP) is an important phenomenon of material behaviour of steel. It may lead to distortion of work‐pieces. As there are open questions in modelling and simulation, TRIP is an important field of current research. There are different modelling approaches. The well‐known Leblond model is implemented in the commercial program SYSTUS (SYSWELD)®. New experiments and investigations show that there are interaction effects between TRIP and classical plasticity which cannot be described by the Leblond model. In this contribution, we compare the Leblond model with an alternative approach, discussing advantages and deficiencies. Moreover, we present some first comparative simulations in 3d settings.
