در این ویدئو به شبیه سازی مرحله به مرحله اتصال تیر به ستون بتنی تقویت شده با میلگرد و CFRP در نرم افزار آباکوس پرداخته ایم. تیر و ستون بتنی به صورت سه بعدی و تغییر شکلپذیر با متریال مدل CDP، میلگردها به صورت پارت وایر و با متریال استیل ...

در  این ویدئو به صحت سنجی و شبیه سازی قدم به قدم فرآیند الکتروهیدرولیک با استفاده از مدل فشار زمان در نرم افزار آباکوس پرداخته ایم. مقاله مورد استفاده در این شبیه سازی در سال ۲۰۱۴ در یکی از ژورنال های الزویر چاپ شده است.شکل‌دهی الکتروهیدرولیکی یک فرایند شکل‌دهی ورق ...

In this tutorial Simulation concrete slab cutting by using a rigid cutter in Abaqus has been investigated.Concrete cutting is a process of controlled sawing, drilling and removal of concrete performed by skilled operators using special saws that use diamond impregnated blades. Unlike the old-fashioned dusty jack hammer method, modern concrete ...

In this tutorial simulation concrete beam-column joints in Abaqus has been studied. Strengthening of existing reinforced concrete structures is now a major part of the construction activity all over the world. The RCC structures constructed across the world are often found to exhibit distress and suffer damage, even before service ...

In this tutorial Simulation steel beam damage under cyclic loading in Abaqus standard has been investigated.Under cyclic loading conditions such as those introduced by earthquake  ground motions, the local buckling is initiated in the compression flange.  However, it disappears and reappears in subsequent cycles. The beam is modeled as three ...

In this tutorial Simulation of p-section concrete beams under contact explosion(CEL) conditions in Abaqus has been studied. Reinforced concrete bridges are the most common type of bridges and have a simple structure, low cost and long durability. Among these bridges, reinforced concrete bridges composed of p-section bridge components are among the ...

In this tutorial numerical simulation of CEL explosion over metal tube in the depth of water in Abaqus has been investigated.An underwater explosion can be divided into two stages: the shock wave and the bubble pulse. Although both inflict severe damage to the adjacent structure, their damage mechanisms are different. Generally, the ...

In this tutorial Prediction model of depth of penetration for alumina ceramics under garnet impact in Abaqus has been studied .The target and projectile were modeled as three dimensional parts .The JH-2 constitutive model was proposed to describe the response of ceramic materials to large strain rate. The JH-2 constitutive model ...

In this video Simulation steel drilling process in Abaqus has been investigated.Drilling process is one of the most required machining techniques that accounts for more than 40 % of the total material removal processes and especially has a high frequency of use in aerospace industries . It is significant to ...

Progressive collapse refers to the failure of one or a group of key structure load-carrying members that gives rise to a more widespread failure of the surrounding members and partial or complete structure collapse. It is defined as the spread of an initial local failure from element to element resulting ...

With the growing use of composites in military, air vehicles and naval structures, sporting goods and the power industry, the comprehension of impact mechanism and dynamic behavior is critical to composite designers and end users. A wealth of knowledge has been published on dynamic impact response of composite materials and ...

Insulated concrete sandwich panels are comprised of two outer concrete wythes and an inner layer of foam insulation. They have been increasingly used because of their advantages of light weight and energy efficiency. Various shear connectors can be used to connect the two outer concrete wythes. More recently, Fiber-Reinforced Polymer ...

Explosions, whether accidental or planned, can cause significant damage to the built infrastructure and result in fatalities to occupants of buildings in close proximity to the center of explosion. The increase in the number of terrorist attacks over the past few decades has led to growing concerns about the performance ...

Honeycomb sandwich structures are broadly used in the aerospace and automotive industries, particularly as energy-absorption materials, and there are limited applications in civil infrastructure, such as highway bridges and building construction. Due to their unique and advantageous properties such as high mechanical performance per unit weight and high energy-absorption capability, ...

In this video you can see Simulation blast loading over concrete slab reinforced by composite layers in Abaqus step by step.With the increased world tension, terrorist bombing attacks or accidental explosions are becoming a large threat to infra-structure such as the important economic, military and civilian facilities. The research on ...
