In this lecture through ten step-by-step tutorials, many aspects of the crack growth like XFEMm H integral, and … in concrete, steel, dam, bone, and…are investigated. All the tutorials are explained from A to Z, each tutorial contains cae, inp, and step-by-step English video. All the tutorials in the package ...

In this tutorial crack growth simulation of bone under three points bending in Abaqus has been studied. Structural analysis of bones is now actively studied by many researchers using the finite-element method (FEM) to better understand the mechanism of bone fractures. Most previous studies, however, only obtained distribution patterns of stress or ...

The critical mechanical characteristics governing the usability of concrete containing wood shavings as aggregates are mechanical strength and durability.There is a renewed interest in the use of wood-based composite materials because of their ability to regulate indoor climate. Numerous studies have shown that the hygroscopic behavior of materials of vegetable ...

In this example we consider an analysis of the Koyna dam, which was subjected to an earthquake of magnitude 6.5 on the Richter scale on December 11, 1967. The example illustrates a typical application of the concrete damage base on traction separation laws. Dam is modeled as two dimensional part ...

In this video Simulation three dimensional crack growth in concrete slab by using XFEM technique in Abaqus software has been studied.Concrete part is modeled as three dimensional part with traction separation behavior which defined in material property. To model crack growth under static load XFEM procedure with planar crack has been ...

 In this tutorial crack modeling and mechanical fracture parameter in the four point bending test in Abaqus has been investigate. Piece has a crack edge with three mm length which under the bending load. In this example two dimensional part has been used and the pieces is modeled with steel material ...

In this video XFEM crack growth in the two Dimensional concrete palate in Abaqus has been simulated. Concrete is modeled as 2D shell element and Separation Traction Low appropriate with crack growth has been used. Dynamic Implicit step is performed and you can see some figures of this simulation at ...

In this video XFEM crack growth in the pressure vessel has been simulated. Pressure vessel geometry imported to Abaqus from Solidworks because of difficulties to modeling it in Abaqus. Aluminum material for pressure vessel with traction separation laws(Maxps) mix with power law evolution to predict crack growth has been used. ...

In this video you can see step by step tutorial of ellipsoid crack in the pressure vessel under internal and external pressure in ABAQUS sofware.The internal pressure is fixed but the external pressure is variable with time and location. For calculation the external pressure we used DLOAD subroutine as function ...

در این ویدئو به شبیه سازی قدم به قدم رشد ترک در یک نمونه CT شکل به روش XFEM در نرم افزار آباکوس پرداخته ایم. برای ماده قطعه از یک نوع کمپوزیت همراه با معیار مناسب برای پیش بینی شکست المان ها برای رشد ترک و مشاهده نمود فیزیکی آن ...
