Stress relief treatment before machining and sawing aluminium direct chill cast products is required to avoid uncontrolled distortion, crack formation and significant safety concerns due to the presence of thermally induced residual stresses created during ...
The influence of welding tensile residual stresses on fatigue crack growth in bridge tubular K-joints is investigated through experimental testing of large-scale specimens. Crack development is monitored using the alternating current potential drop method. ...
This paper investigates the effect of confining stress on rock fragmentation under TBM cutters by numerical simulation. Firstly, based on the characteristics of the force-penetration curve, the confining stress conditions for TBM tunneling are divided into ...
The physical mechanisms underlying the dynamic fragmentation of heterogeneous brittle materials are explored through numerical simulations. The use of computational facilities, rather than experimental or fundamental sciences, ensures the accurate tracking ...
Primary load-bearing glass constructions are often subjected to relatively important in-plane loads, transferred through so-called point-fixed connections. The according in-plane load introduction, structural resistance and failure mechanisms have been stu ...
ASR affected concrete in real structures is usually subject to loads which affect the macroscopic expansion of the material. An experimental study was undertaken using sensors embedded in reactive and non-reactive samples loaded on modified creep frames. N ...
A full rate-dependent cohesive law is implemented in the distinct lattice spring method (DLSM) to investigate the dynamic fracturing behavior of brittle materials. Both the spring ultimate deformation and spring strength are dependent on the spring deforma ...
Fibre reinforced materials are increasingly employed in aerospace, naval and civil structures because of their low weight and high specific strength and stiffness. A major concern is the inherent susceptibility of composite laminates to barely visible dama ...
Welding is an important joining method for the work with metals. During the welding process, the material is heated and deforms plastically which leads a change in microstructure in the heat affected zone, to complex residual stress distributions, and dist ...
The purpose of this paper is to explore the UHPFRC time-dependent behavior under sustained tensile loading at very early age (3 days) and to highlight its sensitivity to the level of loading by laboratory testing and numerical analysis. Uniaxial creep and ...
