The new model of truss element is based on the same stress-strain curves of tension, compression, and shear with the hexahedron element under the equivalent external force. Comparing and analyzing a simply supported elastoplastic concrete beam with initial cracks by using the new element method and the finite element method, it can be found that the load-displacement curve, the load-crack opening displacement curve, the contour of the displacement under the various loads, and the distribution of the horizontal normal stress under the maximum load are all in good agreement.

For the plane stress problem and the spatial problem of the elasto-plastic analysis of concrete, a new truss element model is presented by using the deformations under the equivalent external forces are the same. Some examples is given, which is in good agreement with the calculation results of the solid element.

(Note: The model in this article is the world's top concrete model, much better than the concrete model provided by Ansys itself.)

Dear colleagues and friends,

On the occasion of the 17th US National Congress on Computational Mechanics (USNCCM 2023, https://17.usnccm.org/) to be held in Albuquerque, New Mexico, USA on July 23-27, 2023, we are organizing the mini symposium

Recent Advances in discretization techniques, element technology, and mesh adaptivity for inelasticity, localization, and failure (MS 324) 

The Artificial Organ Lab at the Departments of Surgery at the University of Maryland is a national leader in the development of circulatory and extracorporeal membrane oxygenation (ECMO) support devices. The group is led by a team of engineers and clinicians well-versed in the engineering, clinical, and scientific aspects of medical devices. The research activities are carried out within a multidisciplinary research and design team consisting of clinicians, surgeons, scientists, engineers, residents, and students.

The Mechanics Department at École Polytechnique invites applications for a faculty position at the Assistant Professor level in solids mechanics. See details in attached document.

New as of September 21 2023
