What is Hard Contact Abaqus? | Defining Abaqus Normal Behavior

In Abaqus, “Abaqus normal behavior” defines how surfaces interact perpendicularly when they come into contact, focusing on pressing together, separating, and resisting penetration. A specific type of normal behavior, “hard contact,” (hard contact Abaqus) ensures surfaces do not penetrate each other and no tensile stress is transmitted across the interface, akin to a rigid interaction […]
What is Abaqus Spring Element? | Applying Spring Stiffness Abaqus

Abaqus spring element(s) allow engineers to accurately represent physical springs and idealized axial or torsional components. By coupling forces with displacements or moments with rotations, these elements can exhibit both linear and nonlinear behaviors, making them highly versatile for various applications. From modeling physical springs and structural dampers to restraining rigid body motion and performing […]
Applying Abaqus Velocity | Angular Velocity VS Linear Velocity

Linear velocity refers to how fast an object moves in a straight line, while angular velocity measures the rate of rotation around an axis. Linear velocity is measured in units such as meters per second (m/s), whereas angular velocity is measured in radians per second (rad/s). The main difference is that linear velocity focuses on […]
Abaqus nonlinear analysis VS linear analysis
The world of FEA engineering thrives on precise simulations that mirror real-world scenarios. But a crucial question often arises: when can a straightforward linear analysis provide sufficient results, and when do we need to navigate the intricate world of nonlinearity? Understanding this fundamental distinction is paramount for choosing the right tools within Abaqus and achieving [...] Abaqus convergence issues in simple terms | FEA convergence problem

The meaning of specific internal energy and dissipated inelastic specific energy
In Abaqus, specific internal energy and dissipated inelastic specific energy are key concepts that help capture the energy dynamics in a material. Specific internal energy refers to the internal energy per unit mass, while dissipated energy is the energy converted into other forms and lost from the system. These concepts are essential for analyzing thermodynamic [...] What is Abaqus Small Sliding? | Finite Sliding VS Small Sliding
1. What is Abaqus small sliding and Finite Sliding? In Abaqus, “small sliding” and “finite sliding” refer to different modeling assumptions for contact behavior. Small sliding assumes that the contact surfaces remain nearly parallel and that relative sliding between them is minimal. It implies that the tangential displacements between the contacting surfaces are small compared to [...] ABAQUS vs ANSYS : Difference between Ansys and Abaqus
Difference between Ansys and Abaqus | ANSYS vs ABAQUS When it comes to simulating mechanical models, two names often come up: ABAQUS ANSYS. The question that frequently arises is, "Which one is better? (Ansys vs Abaqus)" This query is commonly asked by engineer designers, particularly beginners, who are seeking guidance. In this article, we, the [...] Most Typically Used Subroutines in Abaqus

Abaqus provides the users with an extensive array of user subroutines regarding standard, explicit (or CFD analyses). For instance, here we introduce some of the most popular and important subroutines in Abaqus/Standard and Explicit. Writing user subroutines with Abaqus will be presented in the last part of the article. However, all user subroutines applicable in […]
