On the evaluation of the shakedown boundary for temperature-dependent elastic properties
No full textA procedure for shakedown analysis in the presence of temperature-dependent elastic properties is proposed. It is based on a kinematic statement derived from a discretized version of the shakedown condition and provides an iterative method for the evaluation of the shakedown boundary. Strictly speaking, only upper bounds are obtained; however, the correct value is detected when the correct inadaptation modality is identified, which can be done in several practical situations, as some examples illustrate
Numerical analysis of fire effects on beam structures
No full textA known finite element model is significantly enriched in order to take into consideration the variations of material parameters that are provoked by elevated temperatures due to fire environment. On the basis of this 'heterogeneity acquired model' a numerical iterative procedure is implemented that permits to describe the performances of beam structures exposed to fire. Efficiency of the proposed model and relevant procedure are shown by some numerical results which are partly and successfully compared with experimental ones obtained by other researchers

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
