Recent beam physics studies on the two-stream e-p instability at the LANL proton storage ring (PSR) have focused on the role of the electron cloud generated in quadrupole magnets where primary electrons, which seed beam-induced multipacting, are expe

In this paper we demonstrate the use of Bezier projection to alleviate locking phenomena in structural mechanics applications of isogeometric analysis. Interpreting the well-known B projection in two different ways we develop two formulations for loc

In this paper we develop the isogeometric Bezier dual mortar method. It is based on Bezier extraction and projection and is applicable to any spline space which can be represented in Bezier form (i.e., NURBS, T-splines, LR-splines, etc.). The approac

In this paper we develop an isogeometric Bezier dual mortar method for coupling multi-patch Kirchhoff–Love shell structures . The proposed approach weakly enforces the continuity of the solution at patch interfaces through a dual mortar method and

Phase-field models have been a topic of much research in recent years. Results have shown that these models are able to produce complex crack patterns in both two and three dimensions. A number of extensions from brittle to ductile materials have bee

In this paper, we present an algorithm to construct enriched Bezier dual basis functions that can reproduce higher-order polynomials. Our construction is unique in that it is based on Bezier extraction and projection, allowing it to be used for tenso

A phase-field model is presented for the study of fatigue crack growth. A crack growth viscosity parameter is introduced into the standard phase-field model for brittle fracture to account for rate- or cycle-dependent crack growth phenomena. A modifi

Phase-field models based on the variational formulation for brittle fracture have recently been shown capable of accurately and robustly predicting complex crack behavior. Their numerical implementation requires costly operations at the quadrature po
