در این ویدئو به شبیه سازی احداث خاکریز و گودبرداری در خاک مرطوب در نرم افزار آباکوس پرداخته ایم. برای مدلسازی از فضای دوبعدی استفاده و پارت خاک و خاکریز به صورت جداگانه ایجاد شده اند. در این مثال خاک به صورت مرطوب فرض شده و به همین دلیل باید اثرات ...

The primary motivation of this study was the development and implementation of an explicit nonlin-ear dynamic finite element based methodology for investigating the crashworthiness of small lightweight rigid impacting into soft soil.The crash dynamics of aircraft are highly dependent on the characteristics of the impact terrain, as different terrains produce ...

In this tutorial consolidation of soil in interaction with concrete pile in Abaqus has been investigated.All parts has modeled in one part and tree zone was created with partition as soil zone,pile and cohesive for modeling interaction between pile and soil interference .Analysis contains three steps. In the first step soil ...

Using backfill soils with cohesive fine contents to build geosynthetic-reinforced soil (GRS) retaining walls for permanent purposes has attracted considerable attention in recent years.Such back fills are considered to be marginal since they contain cohesive fines that have a plasticity index (PI)>6 and mayor may not exceed 15%.If justified, this ...

In this video step by step simulation of embankment construction on saturate soil floor in Abaqus has been done. In the below figure schematic of simulation has been showed. Soil is contained two section as dry and saturate section Elastic material with coulomb-Mohr plasticity for soil has been used. Because ...

In this video Simulation interaction between clay and concrete wall under external pressure in Abaqus has been done.In the below figure schematic of geometry is mentioned To model concrete wall and clay soil  two dimensional space has been implanted.  The concrete wall is modeled as elastic model and clay is modeled ...

In this video pile in interaction with soil under vertical load in Abaqus has been investigated. To model this tutorial two D has been used.Concrete pile is modeled as elastic material and Mohr-Coulomb plasticity with variant elastic depend on elevation for soil has been implanted. Infinite element for modeling area ...

In this video interaction between concrete wall and soil in Abaqus has been investigated.  The wall and soil are modeled as two D parts and elastic material for concrete and variant elastic and plastic material for soil has been used.  This analysis contain four steps that all of them are ...

In this video two dimensional tunneling and earthquake has been simulated in ABAQUS. For modeling soil Coulomb-Mohr plasticity and for liner material concrete has been used. This project is contained six steps and after excavation and place liner in the tunnel, earthquake load has been applied. During the analysis and ...

In this video pile penetration to the soil by CEL(couple Eulerian Lagrabgian) has been simulated. Soil has modeled as eulerian part with Coulomb-Mohr material. Pile has modeled as a 3 dimensional lagrangian part concrete material. Explicit procedure is appropriate for this analysis and two steps has defined , in the ...

In this video CEL explosion inside concrete tunnel in interaction with soil in ABAQUS has been investigated.To perform this analysis Volume Fraction technique to extract TNT amount has been used. Concrete tunnel modeled as a there dimensional with JC material for better performance in explosion  phenomenon.Air modeled as Ideal gas , ...

In this video impact process with DEM approach in Abaqus has been investigated. Impact happened between a sand or soil part and aluminium plate. A sand has modeled as a three dimensional part with DEM element and  just density used for this part. The plate has modeled as shell element. ...

In this video you can see all details about TBM simulation in Abaqus.The lanquage of video is English and we create two part for the analysis. the first part is soil and the second part is liner.we assume 6 stage for this simulation. During the analysis the soil section has ...
