Fatigue and Damage Tolerance of Aircraft Structures.

Research Area

Calvin Rans’ research interests lay in developing a mechanistic understanding of the failure and degradation of lightweight aircraft materials and structures. True structural optimization that aims at minimizing weight without sacrificing safety can only be achieved by a thorough understanding of failure and failure progression. With such knowledge, structures can be designed to fail in a slow, progressive, and obvious manner, enabling failures to be detected and repaired long before they become critical to the safety of the aircraft. This design philosophy is known as Damage Tolerant Design and is the motivating driver for Rans’ work.

Recently, Rans’ work in fatigue and damage tolerance has branched out into the emerging field of Additive Layer Manufacturing (ALM), also commonly known as 3D-printing. The design freedom allowed by this manufacturing technique enables structural designs with complexities and topologies that were previously the realm of science fiction. The technology enables new novel weight-optimized structures, but the question remains how do we certify them? In order to answer this, we need to determine the impact of the new manufacturing method on fatigue, degradation, and durability, and link this to the design and optimization procedure.

    TU Delft's Best Lecturer and Most Innovative Teaching Talent

    Calvin Rans, assistant professor in the Faculty of Aerospace Engineering (AE), has been chosen TU Delft’s Best Lecturer of 2018. He is well known as a very approachable and engaged lecturer, who asks students for feedback in order to further improve his lectures. His students are highly enthusiastic about the courses he lectures on: his first year course Mechanics of Materials is taught in a blended way, linking in with students’ questions, and he manages to make the ‘tough’ second-year course, Structural Analysis & Design, interesting partly by using examples that bring the theory to life.
