In many cases, in addition to manufacturing process analysis, it is also necessary to examine the mechanical or thermal load capacity of new components. With static, strength, dynamic, thermal, topology and shape optimization solutions based on the finite element method, we can efficiently design plastic parts with the help of Altair's simulation software package. With the Altair Partner Alliance even the use of additional third-party software for specific problems is possible. Material-specific strength assessment of plastic components is often a problem in practice. With the Altair solvers and partner software, a well-founded static and fatigue strength assessment can be performed and even complex properties, such as fiber orientation, can be taken into account.
