Geostatic stress field procedure is the first and most important step for numerical simulation of geotechnical engineering, which greatly influences results. Traditional methods often fail when model complex. In this paper, based on finite element method (FEM) software ABAQUS, failure reasons four commonly used geostatic are studied. According to analysis results, a new set methods, can provide...

The use of 3D printing in modular building connections is a novel and promising technique. However, the performance printed steel has not been investigated adequately to date. Therefore, this paper presents three-dimensional finite element model (FEM), using multi-purpose software Abaqus, study effect different geometrical material parameters on ultimate behaviour (herein named 3DMBC) wire arc ...

deep drawing of cylindrical shapes with high limiting drawing ratio (ldr) values is relatively difficult. annealing is a further operation, which in turn adds costs and consumes significantly time to the forming process. in the present work, cylindrical cups from brass sheet were made with only limited anneal during few steps, but having ldr of 9 that is about 2 times higher than previous works...

I. ABSTRACT This paper presents an investigation of predictive modeling of space structures for structural health monitoring (SHM) with piezoelectric wafer active sensors (PWAS) transducers. The development of a suitable SHM system for complex space structure is not trivial; creating a robust SHM capability requires at least: (a) flexible accommodation of numerous configurations; (b) detection ...

Board-level solder joint reliability is very critical for handheld electronic products during drop impact. In this study, board-level drop test and finite element method (FEM) are adopted to investigate failure modes and failure mechanisms of lead-free solder joint under drop impact. In order to make all ball grid array (BGA) packages on the same test board subject to the uniform stress and str...

The main objective of this paper is to study the effect of extrusion parameters (extrusion stresses and temperature) and die geometry, i.e. extrusion radius, on the extruded aluminum quality using FEM Simulation Technique. For this purpose, the general FEA Software ABAQUS was used to set up the finite element model of the warm aluminum extrusion in two dimensions (2D). Aluminum alloy Al-2014 wa...

A comprehensive model of electrical discharge machining has been used for simulating the crater size during process materials Aluminum, Brass and die steel D2. It is very difficult by theoretically to analysis temperature distribution in whole work -piece because its complexity a single occurs short time. novel proposed with realistic condition such as plasma radius, Gaussian heat flux dependen...
