“…Later, this subject is applied in elastic-plastic with large displacement [1, 3,4,163] and Direct Strength Method, DSM, [9,119]. Duan et.al also developed a GBT elastic-plastic formulation based on B-Splines curves [54,56] and impact load analysis [57]. The non-linear physical GBT is beyond of this dissertation's scope.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Given these characteristics, advanced computational methods are used to analyze the behavior of thin-walled structures, capturing deformations, buckling, and interactions between structural modes. Generalized Beam Theory (GBT) is one such method, allowing decomposition of beam deformations into individual modes such as local buckling, global buckling, and torsion [ 13 , 14 , 15 , 16 ]. The Semi-Analytical Finite Strip Method (SAFSM) [ 17 ] divides the element into strips with simplified displacement models: analytically treated across the width and numerically along the length.…”

“…There are several computational methods that can be applied in the analysis of structures made of thin-walled profiles: The Generalized Beam Theory (GBT), specifically designed for the analysis of thin-walled rod structures. The GBT effectively deals with complex deformations and buckling in such elements [12][13][14][15]. The SAFSM (semi-analytical finite strip method) [16] is a semi-analytical structural analysis method for thin-walled elements.…”
