Applications of an improved estimator of the constitutive relation error to plasticity problems
Gallimard, L.,Ladeveze, P.,Pelle, J.P. Techno-Press 2002 Structural Engineering and Mechanics, An Int'l Jou Vol.14 No.4
This paper presents several applications of an improved estimator of the constitutive relation error (CRE) for plasticity problems. The cumulative aspect of the CRE estimator with respect to time is analyzed and we propose a first analysis of the local effectivity indexes of the CRE estimator in plasticity.
Extension of the variational theory of complex rays to orthotropic shallow shell structures
Cattabiani, Alessandro,Barbarulo, Andrea,Riou, Herve,Ladeveze, Pierre Techno-Press 2016 Advances in aircraft and spacecraft science Vol.3 No.3
Nowadays, the interest of aerospace and automotive industries on virtual testing of medium-frequency vibrational behavior of shallow shell structures is growing. The development of software capable of predicting the vibrational response in such frequency range is still an open question because classical methods (i.e., FEM, SEA) are not fully suitable for the medium-frequency bandwidth. In this context the Variational Theory of Complex Rays (VTCR) is taking place as an ad-hoc technique to address medium-frequency problems. It is a Trefftz method based on a weak variational formulation. It allows great flexibility because any shape function that satisfies the governing equations can be used. This work further develops such theory. In particular, orthotropic materials are introduced in the VTCR formulation for shallow shell structures. A significant numerical example is proposed to show the strategy.
