Abaqus for beginners (Mechanical Engineering)-Free Version

You can watch demo here.

This lesson is very attractive to the users of finite elements. In this lesson, you will be familiar with the finite element completely. First, starts with some simple examples like meshing an aerial structure, calculating the circumference of a circle, and displacement calculation of a structure with geometric complication. Then, it discusses using finite element tools to solve problems step by step.

Furthermore, this lesson explains about different types of elements in terms of shape, element and node, freedom degree, and finite element is used for two types of problems. They and FEM instruction will be described to solve a difficult shape step by step. The users must know that using the FEM method has its advantages and disadvantages.

They will be explained completely with examples and figures. In the end, the degree of freedom and plane stress element and plane strain with problems that can use these elements will be described completely. It is necessary to know that one of the most important issues of using simulation software is studying convergence. The description of studying convergence is the last theory content in this lesson.

Two workshops are investigated in this lesson: In the first one, a three-dimension truss is simulated to model a 3D structure in space, using the software tree diagram, reading results, etc. In the second one, a sheet undergoes plane stress and the notes related to plane elements, applying tensional extensive load, reading results in a curved path, symmetric condition and model simplification, software technique for investigating convergence, and so on will be studied.

• This lesson focuses on elements in the FEA simulation topic. At first, it explains the types of characteristics of elements, including family, degree of freedom, number of nodes, formulation, and integration completely. Then, the beam element and its items of use will introduce. The beam element can be used in two different formulations, Bernoulli and Timoshenko with different theories and different applications which will be explained in detail.
• In the first workshop of this Abaqus course, a single clamped beam under concentrated force is simulated. The results from simulation and formulation analysis will be compared.
• In the second workshop, beam simulation with the beam element and continuum element will be done and compared. The workshop describes the simulation with continuum element, beam element simulation tips, extracting moment results, force along the beam and cross-section, and parts observation with different colors; and also, explains beam modeling in a dynamic analysis which includes loading, and getting HTML results from simulation procedure. (FEM simulation / FEA simulation)

• This lesson is one of the most important lessons in this FEM simulation tutorial package. Explicit and standard solvers will be completely discussed in this Abaqus course lesson. In this FEA training, in the first step, it will be explained to choose an appropriate solver for each example by considering solver capability.
• The key differences between these two solvers are described in solving different types of problems and the field element type of analysis, using contact, solving method, and so on. In the next step, the influence of mesh size on the speed of analysis for the two solvers is investigated.
• It has been tried in a simple problem the solving process with two solvers, standard and explicit, to be completely explained. Therefore you will be completely familiar with the function of these two solvers.
• A deep drawing analysis is done by using the explicit solver in the workshp. In this workshop, different contents are explained as listed below: rigid body and related points, using information extracted from simple tensile stress in a laboratory in the inputs of software, Axsim element, and related points, defining contact, assembling, defining plasticity and so on.

• In this lesson, very important tips about explicit solvers are studied. In the first step, different types of analysis are explained which are done by the dynamic explicit solver. Furthermore, the concept of stable time increment and calculation method will be described with examples completely and precisely.
• In some problems, the speed of analysis can be increased with the help of different techniques, such as mass-scale and load rate scaling. These two techniques are explained completely. Some tips are passed on calculating optimal values for use in these two techniques. In the end, some points are explained about energy balance and remaining the problem in the quasi-static (versus Dynamic) state.
• In the first workshop, the optimal time for deep drawing analysis is calculated and applied. In this analysis, two methods of increasing the analysis speed such as mass-scale and rate scaling are studied. 
• The plane strain element is used in the second workshop, and methods of increasing the analysis speed are investigated. Furthermore, rolling modeling tips to decrease the thickness along the rolling shelf are presented. In the end, the energy balance is checked to prevent it from becoming dynamic. I hope you have not gotten tired of our explanation about this complete Abaqus course.
