3D Laser Shock Peening – A new method for the 3D control of residual stresses in Selective Laser Melting

Roland Logé, Jamasp Jhabvala, Christian Leinenbach, Eric Boillat, Nikola Kalentics

This paper describes a hybrid additive manufacturing process – 3D Laser Shock Peening (3D LSP), based on the integration of Laser Shock Peening (LSP) with selective laser melting (SLM). The well-known tensile residual stresses (TRS) in the as – built (AB) ...

Stress generation during the quenching of large AA2618 forgings: Finite element computations and validation against neutron diﬀraction measurements

Jean-Marie Drezet, Nicolas Paul Henry Chobaut, Denis Carron

Solutionising and quenching are key steps in the fabrication of heat treatable aluminium parts such as AA2618 compressor impellers for turbochargers. Quenching not only dictates the mechanical characteristics of the product but also induces residual stress ...

Effects of residual stresses on the tensile fatigue behavior of concrete

Jean-François Molinari, Mauro Corrado

The influence of Eigenstresses due to drying shrinkage on the development of residual deformations characterizing the tensile fatigue behavior of concrete is analyzed. During the loading phase the Eigenstresses are locally released around the cracks induci ...

Measurements and modelling of residual stresses during quenching of thick heat treatable aluminium components in relation to their precipitation state

Nicolas Paul Henry Chobaut

In the fabrication of heat treatable aluminium parts, solutionising and quenching are key steps in order to obtain the required mechanical characteristics. Fast quenching is necessary to avoid coarse precipitation as this one reduces the mechanical propert ...

High Performance Computing Simulations of Dynamic Fragmentation in Brittle Materials

Marco Vocialta

The aim of this thesis is to investigate the mechanisms behind dynamic fragmentation. This phenomenon occurs in a material when a blast or impact loading nucleates multiple cracks, whose propagation and coalescence break the specimen into fragments. Althou ...

Neutron Diffraction Measurement of As-Cast Residual Stresses in Aa7050 Rolling Plate Ingots: Influence of A Wiper

Jean-Marie Drezet

During casting, thermally induced deformations give birth to ingot distortions and residual stresses. For some high strength alloys, ingot cracking can happen during casting per se or during cooling down. Ingot distortions such as rolling face pull-in, but ...

Numerical modelling and experimental investigation on welding residual stresses in large-scale tubular K-joints

Alain Nussbaumer, Jean-Marie Drezet, Claire Acevedo

This paper is devoted to the experimental and numerical assessment of residual stresses created by welding in the region surrounding the weld toe of tubular K-shaped joints (i.e. region most sensitive to fatigue cracking). Neutron-diffraction measurements ...
