A 3D finite element (FE) analysis technique using ABAQUS is chosen to explore the dynamic behavior of a beam under impact load. A beam, for which the impact dynamic test was conducted by Kishi (2004), is selected to develop a solid element FE model. FE analyses were performed implementing ABAQUS Explicit (2004) programming tool to predict the dynamic responses under the pressure amplitude intro...

Concrete is a versatile material having number of desirable properties, so widely preferred in construction industry. But major disadvantage that under severe vibrations such as earthquakes it gets cracked and concrete has poor modification repair quality. Therefore some or strengthening must be performed damaged element stand for further useful life. Many civil structures are no longer conside...

An alternative remeshing methodology for 3D Abaqus explicit analyses which utilizes mesh mapping is presented. Excessive element distortion in 3D large deformation analyses necessitates remeshing, however in Abaqus explicit, the standard 3D remeshing techniques limits the analyst’s choice of element type. The presented technique allows remeshing of 3D perfectly plastic fully integrated higher o...

Now a days product development using prototype methods for actual usage is a growing concept in engineering. Present work deals with simulation of Compact Tension specimen to get fracture parameters J – integral and Stress intensity factors of product built by polyjet technology 3D printer additive manufacturing system. FEA simulation is carried out with the help of Abaqus software by simulatin...

A computational model of the human head has been developed by Simpleware and the U.S. Naval Research Laboratory (NRL) to simulate head impact. The head model was generated using high-resolution scan data, segmentation and image-based meshing techniques, and has been used in Abaqus for a range of simulations. The NRL/Simpleware head model addresses several key limitations of existing techniques ...

Biomechanical model of soft tissue derived from experimental measurements is critical for developing a reality-based model for minimally invasive surgical training and simulation. In our research, we focus on developing a biomechanical model of the liver under large tissue deformation. This paper presents the experimental apparatus, experimental data, and methods to model the experimental data ...

In this paper, we introduce an implementation of the extended finite element method for fracture problems within the finite element software ABAQUSTM. User subroutine (UEL) in Abaqus is used to enable the incorporation of extended finite element capabilities. We provide details on the data input format together with the proposed user element subroutine, which constitutes the core of the finite ...
