Stress-Strain diagrams for non-convex particles [PDF]

EPJ Web of Conferences, 2017
While most granular materials in nature and technology consist of non-convex particles, the majority of discrete element (DEM) codes are still only able to cope with convex particles, due to the complexity of the computational geometry and the occurrence

Stress-Minimizing Orthogonal Layout of Data Flow Diagrams With Ports [PDF]

Lecture Notes in Computer Science, 2014
We present a fundamentally different approach to orthogonal layout of data flow diagrams with ports. This is based on extending constrained stress majorization to cater for ports and flow layout. Because we are minimizing stress we are able to better display global structure, as measured by several criteria such as stress, edge-length variance, and ...

Stress-Strain Diagrams of Concrete Under Repeated Loads With Compressive Stresses

Procedia Engineering, 2015
AbstractThe article discusses the general characteristics of the deformation of concrete under repeated cyclic loads of compressive stresses observed in the experiments executed by the authors, as well as domestic and foreign researchers. Based on experimental data of fixed and variable levels of stress, limits have been defined for reference points of

Experimental and Numerical Analysis of Forming Limit Diagram (FLD) and Forming Limit Stress Diagram (FLSD)

Materials Sciences and Applications, 2011
In this work, forming limit diagram for aluminum alloy 3105 is performed experimentally and forming limit based on stress (FLSD) calculated from strains that resulted from experimental procedure. In addition, numerical prediction by ductile fracture criteria using simulation is considered and it is shown that they are well suited with the experimental ...

Limit conditions on local failure of nuclear containment steels (Notched round-bar tensile tests for base metals and weld joint materials)

Nihon Kikai Gakkai ronbunshu, 2023
Tensile tests were conducted for notched round-bar specimens to acquire the limit conditions of local failure, which is ductile failure after large local deformation for three types of steel, SGV480, SPV490 and SGV410, for nuclear containment structures.
