STRUCTURAL DURABILITY
COMPONENT RELATED MATERIAL BEHAVIOUR UNDER CONSTANT AND VARIABLE AMPLITUDE LOADING
by Prof. Dr. C.M. Sonsino, Fraunhofer-Institute for Structural Durability (LBF), Darmstadt
Summary
The aim of this lecture is to introduce advanced students to the component related material behavior, which depends on the design, manufacturing and
service loading with constant and variable amplitudes. In practice, the majority of the failures are caused by faults in the geometrical design
of components in connection with an insufficient balance between mechanical loading, environment, shape, local stresses, material and manufacturing.
For this reason, service failures can most often be avoided if the principal influencing parameters regarding the strength behavior are properly taken
into account during construction.
Based on the fundamentals of structural durability and the interplay of the most important influencing parameters, an understanding of the problem
relating to design, selection of manufacturing technology and material, fatigue life and reliability will be imparted by means of practical examples.
Content of Examination of the Lecture:
Structural Durability
Component Related Material Behaviour under Constant and Variable Amplitude Loading
Definition and parameters of structural durability, statistics and safety concepts, notches, mean-stresses, damage accumulation, fatigue life calculation,
surface treatment (thermal, thermo-chemical, mechanical), surface state, residual stresses, size effect, environment, strength hypotheses, design
concepts (nominal, structural, local, fracture mechanical), steels, aluminium, sintered steels, examples about component design
