Abstract: Shakedown is a cyclic phenomenon, and for its analysis it seems natural to employ a cyclic analysis method. Two problems are associated when this direct approach is used in finite element ...

Abstract: A simple and systematic procedure is proposed for shakedown analysis using a combination of linear and nonlinear finite element analysis (FEA). The method can identify the boundary between the ...

Abstract: A new one‐dimensional model for random cyclic compression in concrete is developed. The model determines several geometrical loci in the uniaxial stress‐strain plane that govern the unloading‐reloading curves. The model ...

Abstract: A new one‐dimensional model for random cyclic tension in concrete is developed. The model determines several geometrical loci, defined as focal points, in the uniaxial stress‐displacement plane, which are used to compute ...

Abstract: The tensile strength of concrete is receiving an increasing amount of attention since the loading capacity and durability of structures are being studied more thoroughly, and since nonlinear fracture mechanics and numerical ...

Abstract: There is a lack of information about the behavior of cracked concrete subjected to in‐plane sustained shear loading. Tests are conducted on 46 push‐off specimens, each provided with a central crack, widths less than 0.10 ...

Abstract: A theoretical model is presented, analyzing in‐plane sustained shear tests on push‐off specimens, each provided with a central crack. The tests are described by an extended version of Walraven's two‐phase model accounting ...

Abstract: The acoustic emission (AE) technique can be a useful method for the investigation of local damage in materials. One of the advantages compared to other techniques is the recording of the damage process during the entire ...

Abstract: Some Class I CANDU heat exchanger tubesheets experience very high in-plane thermal gradients under Level A/B transients. If the thermal stresses exceed the ratcheting limit of the ASME Boiler ...
