Abaqus Simulation of Cracking in Large-Size Profiles During Pultrusion

 250.0

Pultrusion is a crucial task for producing constant-profile composites by pulling fibers through a resin bath and heated die. Simulations play a vital role in optimizing parameters like pulling speed and die temperature to enhance product quality and efficiency. They predict material property changes and aid in process control, reducing reliance on extensive experimental trials. However, simulations face challenges such as accurately modeling complex material behaviors and requiring significant computational resources. These challenges underscore the need for precise simulation methods to improve Pultrusion processes. This study employs ABAQUS with user subroutines for detailed mechanical behavior simulations, including curing kinetics and resin properties. Key findings include insights into crack formation, material property changes, and optimization strategies for enhancing manufacturing efficiency and product quality. This research provides practical knowledge for implementing findings in real-world applications, advancing composite material production.

Abaqus convergence tutorial | Introduction to Nonlinearity and Convergence in ABAQUS

 120.0

This package introduces nonlinear problems and convergence issues in Abaqus. Solution convergence in Abaqus refers to the process of refining the numerical solution until it reaches a stable and accurate state. Convergence is of great importance especially when your problem is nonlinear; So, the analyst must know the different sources of nonlinearity and then can decide how to handle the nonlinearity to make solution convergence. Sometimes the linear approximation can be useful, otherwise implementing the different numerical techniques may lead to convergence.

Through this tutorial, different nonlinearity sources are introduced and the difference between linear and nonlinear problems is discussed. With this knowledge, you can decide whether you can use linear approximation for your nonlinear problem or not. Moreover, you will understand the different numerical techniques which are used to solve nonlinear problems such as Newton-Raphson.

All of the theories in this package are implemented in two practical workshops. These workshops include modeling nonlinear behavior in Abaqus and its convergence study and checking different numerical techniques convergence behavior using both as-built material in Abaqus/CAE and UMAT subroutine.

Simulation of pitting corrosion with scripting in Abaqus

 230.0
(3)
Pitting corrosion is a form of extremely localized corrosion that leads to the random creation of small holes in metal. It can occur with random sizes and distributions, typically modeled as conical or cylindrical shapes. This type of corrosion reduces the strength of structures and increases stress concentration. So, it can lead to various destructive effects such as pipes bursting and reduced resistance to internal pressure. By pitting corrosion simulation, you can assess how corrosion affects stress, vibration, heat transfer, and other factors. This is crucial for enhancing the durability and safety of structures such as storage tanks, shafts, tubes, pipes, and other industrial components. This tutorial includes two scripts for pitting corrosion analysis. They help you to conduct Abaqus pitting corrosion simulation for different examples including a simple plate and a shaft.

Abaqus User element tutorial | UEL advanced level

 270.0
(3)
User element (UEL) subroutine (user-defined element) is the highest level of a subroutine that Abaqus offers to its users. This subroutine allows the user to program the basic building block of a finite element simulation. This subroutine becomes very powerful when the user wants to implement a type of element that is not available in Abaqus. Using this subroutine, user can define different types of shape functions, introduce element technology that is not available in Abaqus, or simulate multiphysical behavior that is not possible otherwise. This Abaqus user element tutorial package will give a brief introduction to the user element subroutine followed by theory and algorithm to write subroutine small strain mechanical analysis. First, we will highlight the UEL element stiffness matrix and element residual vector which are to be programmed in the first example. We will also cover shape functions and numerical integration. Next, we’ll talk about UEL inputs and outputs. The first example contains the detailed development procedure of a general-purpose subroutine for 2D plane-strain and 3D simulations using triangular, quadrilateral, tetrahedral, and hexahedral type of elements with reduced and full integration scheme. The second example demonstrates the procedure to build UEL-compatible model in Abaqus/CAE. It also demonstrates how to apply complicated boundary conditions with UEL as well as perform Abaqus analysis on structures which has standard and user elements. As an outcome, user can write their own UEL subroutine afterwards using this program as template.

Modal and Frequency Analysis in Abaqus | Abaqus modal Analysis

 70.0
Modal analysis is a technique used to understand how structures and systems vibrate when subjected to forces. It identifies natural frequencies, which are frequencies at which a system vibrates without external excitation, and mode shapes, representing unique patterns of motion. Engineers use modal analysis simulation to design systems resistant to unwanted vibrations, preventing resonance and potential damage. Frequency response analysis evaluates a structure's reaction to specific excitations across varying frequencies, aiding in design optimization to mitigate fatigue damage caused by vibrations. In Abaqus software, Abaqus modal analysis identifies natural frequencies (Abaqus natural frequency) and mode shapes, while frequency response analysis predicts a structure's response to excitation across a frequency range. In Abaqus modal analysis tutorial package, there are several modal analysis examples (modal analysis example): Workshop 1 analyzes the natural frequency of a water transfer tube to predict resonance occurrence or potential issues from vibrations. Workshop 2 simulates the dynamic analysis of a frame under a sudden load, determining modes, natural frequencies, and transient dynamic response. Workshop 3 simulates free and forced vibrations of a wire under harmonic excitation, examining resonance phenomena with preloading and spring-damper configurations. These workshops demonstrate practical applications of modal and frequency response analyses in structural dynamics simulation and design.
