The beam finite element with five nodal degrees of freedom
Magazine of Civil EngineeringThe article presents comparative calculations of reinforced concrete beams using two types of beam finite elements: with three and five nodal degrees of freedom. Calculations were performed both taking into account the concrete and reinforcement physical

Generating Random Elements of Finite Distributive Lattices
, 1997 This survey article describes a method for choosing uniformly at random from any finite set whose objects can be viewed as constituting a distributive lattice. The method is based on ideas of the author and David Wilson for using ``coupling from the past'

Different forms of metric characterizations of classes of Banach spaces [PDF]
, 2011 For each sequence X of finite-dimensional Banach spaces there exists a sequence H of finite connected nweighted graphs with maximum degree 3 such that the following conditions on a Banach space Y are equivalent: (1) Y admits uniformly isomorphic ...

ELEMENTS: A high-order finite element library in C++
SoftwareX, 2019 We discuss the creation and implementation of a generalized library, named ELEMENTS, of mathematical functions for supporting a very broad range of element types including: linear, quadratic, and cubic serendipity elements in 2D and 3D; high-order ...

Conservative Subgroup Separability For Surfaces With Boundary
, 2012 If F is a surface with boundary, then a finitely generated subgroup without peripheral elements of G = {\pi}_1(F) can be separated from finitely many other elements of G by a finite index subgroup of G corresponding to a finite cover F' with the same ...

Thermoelectric Modules Incorporating MgAgSb and Mg3(Sb,Bi)2 Synthesized Using a Melting Method
Advanced Engineering Materials, EarlyView.A scalable synthesis method for a thermoelectric material of MgAgSb is established. A thermoelectric power module of MgAgSb/Mg3(Sb,Bi)2 is fabricated, showing the conversion efficiency of 7.4% at ΔT = 315 K. The performance is comparable to conventional Bi2Te3 modules when they are operated with an air‐cooled heat exchanger.

Probabilistic finite elements [PDF]
In the Probabilistic Finite Element Method (PFEM), finite element methods have been efficiently combined with second-order perturbation techniques to provide an effective method for informing the designer of the range of response which is likely in a ...

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response
Advanced Engineering Materials, EarlyView.A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...
