Structural Optimization Guide: Building Smarter, Lighter, and Stronger Designs
Introduction Structural optimization is an established engineering methodology used to improve structural designs by systematically changing material distribution, geometry, or member sizing to meet defined performance targets. In most engineering organizations, optimization is no longer “nice to have.” It is a practical way to reduce mass, improve stiffness, control stress hotspots, and increase overall efficiency […]
What Is Thermal Stress Analysis? Abaqus and ANSYS Guide Explained
Thermal stress analysis is the process of evaluating mechanical stress caused by temperature changes in materials and structures. When materials heat up, they tend to expand; when they cool down, they contract. If this expansion or contraction is unconstrained, the material simply changes size without any stress. But if parts of a structure are restrained […]
Life Assessment and Creep Damage Analysis of Welded Components
Life Assessment and Continuum Damage Creep Analysis of Welded Components By: Saman Hosseini – Expert in creep welding simulation, fatigue, and FFS Level 3 assessments. Introduction Imagine a high-pressure steam pipe in a power plant, with countless welded joints, all enduring red-hot temperatures for decades. How do engineers predict whether those welds will survive or […]
Fatigue Life Prediction in FEA – A Comprehensive Guide (ANSYS, Abaqus, fe-safe & More)
Introduction Fatigue failure is one of the most common causes of unexpected breakdowns in engineering structures subjected to cyclic loading. Even when stresses are well below a material’s yield or ultimate strength, repeated load cycles can initiate small cracks that grow over time, eventually leading to catastrophic fracture. Predicting fatigue life (the number of cycles […]
Additive Manufacturing & Welding Simulation in FEA: A Comprehensive Guide
Additive manufacturing (often called 3D printing) and traditional welding are both processes that involve melting and fusing material. These processes offer incredible possibilities (from printing intricate medical implants to welding critical oil-and-gas pipelines), but they also introduce challenges like residual stresses, distortion/warping, and complex thermal histories. Finite Element Analysis (FEA) has become an indispensable tool […]
Predictive Corrosion Modeling in Pipes and Vessels Using AI and Finite Element Methods
Revolutionizing Corrosion Simulation in Pipes and Vessels: Leveraging AI and FEM Software for Accurate Predictive Maintenance Corrosion is one of the most challenging issues in engineering, especially when considering its long-term impact on the integrity of critical infrastructure, such as pipes, pressure vessels, and marine structures. The need for advanced methods to simulate corrosion and […]
Fitness for Service (FFS) in Asset Integrity
The Role of Fitness-for-Service (FFS) in Asset Integrity Fitness-for-Service (FFS) analysis is a structured engineering approach to determine if equipment with flaws or damage can continue to operate safely and reliably. It is a crucial part of asset integrity management, especially in high-risk sectors like oil & gas, power generation, and manufacturing. Over an asset’s […]
What is the Best FEA Software in 2025
What is the Best FEA Software in 2025 Finite Element Analysis (FEA) software has become a cornerstone of modern engineering, allowing designers to virtually test how products and structures behave under various forces and conditions. By breaking complex structures into smaller “finite” elements and simulating physical phenomena (like stress, heat, or fluid flow) on each […]
Abaqus vs ANSYS: Which Simulation Software Is Better in 2025?
Introduction In modern engineering workflows, simulation tools are indispensable. They enable engineers to virtually test designs under various conditions, reducing the need for costly physical prototypes and accelerating innovation. Two of the leading finite element analysis (FEA) platforms are Abaqus and ANSYS, each with decades of development behind them. In 2025, these tools remain at […]
Cold Gas Spraying & Shot Peening: A clear, practical guide to simulating high-velocity impacts
Cold gas spraying and shot peening may look different at first glance — one deposits material, the other changes the surface — but both are driven by the same physics: high-velocity impacts that create intense, highly localized plastic deformation. That makes them perfect candidates for finite-element simulation with tools like Abaqus, Ansys, COMSOL, or other […]
