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 Simulation three dimensional fatigue phenomenon in Abaqus by using Paris law has investigated.  Metal fatigue is the process by which a material is slowly damaged by stresses and strains that are less than those needed to actually break the material apart. For example, a steel wire might be ...

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 ...

در این ویدئو به شبیه سازی رشد ترک در یک تیر(مخلوط بتن و خاک اره یا چوب) به روش XFEM در آباکوس در نرم افزار آباکوس پرداخته ایم. تیر به صورت سه بعدی مدل شده و تحت خمش سه نقطه ای قرار گرفته است . برای ایجاد جسم متحرک  نیز یک ...

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 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. ...
