“…However, fatigue constraints have not been used that extensively in structural optimization problems. Some authors that have used structural optimization in order to find designs that fulfil fatigue life aspects are for example Kaya et al [17], where a failed clutch fork was investigated and compliance based topology optimization followed by shape optimization by the response surface method was used to achieve a design with a lower von Mises stress. The fatigue analysis was made using the software MSC Fatigue [23] and a constant amplitude load curve.…”

We present a contribution to a relatively unexplored application of topology optimization: structural topology optimization with fatigue constraints. A probability based high-cycle fatigue analysis is combined with principal stress calculations in order to find the topology with minimum mass that can withstand prescribed variable-amplitude loading conditions for a specific life time. This allows us to generate optimal conceptual designs of structural components where fatigue life is the dimensioning factor.We describe the fatigue analysis and present ideas that make it possible to separate the fatigue analysis from the topology optimization. The number of constraints is kept low as they are applied to stress clusters, which are created such that they give adequate representations of the local stresses. Optimized designs constrained by fatigue and static stresses are shown and a comparison is also made between stress constraints The paper is written with focus on structural parts in the avionic industry, but the method applies to any load carrying structure, made of linear elastic isotropic material, subjected to repeated loading conditions.

-To design a lighter brake disc than the existing models used in general two wheelers is the main objective of this paper. The newly optimized brake disc is compared with existing BAJAJ Discover125M disc. Topology optimization for weight reduction was performed by using Altair INSPIRE 9.5 software and the newly optimized disc was analyzed in ANSYS16.0.Using this method a new light-weight brake disc is designed. The results of the design shows that the weight of a new brake disc is 26.68% less as compared to the existing brake disc and it has similar performance as the existing disc.

“…Despite these obvious industrial needs, as pointed out in Holmberg et al (2014), there is not a wide literature about fatigue failure in topology optimization, although some interesting issues were explored concerning shape optimization, see e.g. Mrzygold and Zielinski (2006), Kaya et al (2010), Grunwald and Schnack (1997). The work by Holmberg et al (2014) introduces probability-based fatigue constraints, which are aggregated through the adoption of stress clusters.…”

This work investigates a simplified approach to cope with the optimization of preliminary design of structures under local fatigue constraints along with a global enforcement on the overall compliance. The problem aims at the minimization of the weight of linear elastic structures under given loads and boundary conditions. The expected stiffness of the optimal structure is provided by the global constraint, whereas a set of local stress-based constraints ask for a structure to be fatigue resistant. A modified Goodman fatigue strength comparison is implemented through the same formalism to address pressure-dependent failure in materials as in Drucker-Prager strength criterion. As a simplification, the Sines approach is used to define the equivalent mean and alternating stresses to address the fatigue resistance for an infinite life time. Sines computation is based on the equivalent mean and alternate stress depending on the invariants of the stress tensor and its deviatoric
