Seeking light and transparent bridge designs, engineers and architects have found an efficient and artistic way to fulfill their requirements: steel tubular bridges. In these modern tubular truss bridges, welded K-joints have been shown to be critically su ...
The International Fusion Materials Irradiation Facility (IFMIF) is an intense high-energy neutron source dedicated to the development and qualification of materials for the first generation of fusion reactors. The target facility will consist of a high flu ...
We derive a three-dimensional constitutive theory accounting for length-scale dependent internal residual stresses in crystalline materials that develop due to a non-homogeneous spatial distribution of the excess dislocation (edge and screw) density. The s ...
Multiaxial experiments are performed on replicated aluminium foam using a custom-built apparatus. The foam structure is isotropic, and features open monomodal pores 75 mu m in average diameter. Plane stress (sigma(1), sigma(2), sigma(3) = 0) and axisymmetr ...
The gamma surfaces in the pyramidal I {1 -1 0 1} and II {1 1 -2 2} planes for hexagonal close packed Mg have been calculated using two embedded-atom-method potentials and by ab initio methods, and reasonable agreement is obtained for key stacking fault ene ...
The cyclic behaviour of 400 mu m pore size replicated aluminium foam is assessed in tension-tension fatigue with a stress ratio equal to 0.1, keeping the load amplitude constant, for relative density values comprised between 0.175 and 0.220. The number of ...
In this work we have studied brittle fracture in high-chromium reduced activation tempered martensitic steels foreseen as structural materials for thermonuclear fusion reactors. Developing the adequate materials that can withstand the severe irradiation co ...
A new model considering fixed and interlocked cracks for the analysis of reinforced concrete (RC) cracked membrane elements is presented. The model can be regarded as an extension of the cracked membrane model proposed by Kaufmann and Marti. Its value lies ...
The creep of a dislocation on its glide plane is essentially controlled by three different stress fields: the external applied stress, the internal stress field due to a multi-scale hierarchy of different obstacles (the structural defects acting on the dis ...
In fusion power reactors, the plasma facing and breeding-blanket components will suffer intense irradiation by 14MeV neutrons. These high-energy fusion neutrons will produce atomic displacement cascades and nuclear transmutation reactions inside the irradi ...
