利用Abaqus CAE对圆柱形储罐中的晃动进行模拟
Liquid sloshing is the back-and-forth movement of a liquid inside a container when the container itself is moved or shaken; in this case, in a cylindrical tank “the movement of the free surface of a liquid inside a tank due to earthquake acceleration,” and its “height… is a critical factor in designing liquid storage tanks, […]
Abaqus Python 脚本编写完整指南
Imagine you need to run the same Abaqus analysis 50 times with small changes. Doing that by hand could take hours or even days. With Abaqus Scripting, it can take minutes. Abaqus Python scripts let you tell Abaqus what to do step by step. You can automate model creation, run parametric studies, and process results — all […]
Abaqus螺栓加载教程 | 加载、预紧和连接
Bolted joints are everywhere, from cars and machines to buildings and bridges. But bolts don’t just hold things in place. They carry load, stretch under tension, and can even fail. So, when we simulate them, we need to do it right. Abaqus gives us several ways to model bolts, especially when it comes to preload. […]
耦合欧拉-拉格朗日方法完整指南 + Abaqus 模拟技巧
Simulating interactions between fluids and solids can be tricky, especially when materials undergo large deformations or impacts. Traditional methods often fall short when things start to move too much, stretch too far, or mix together. That’s where the Coupled Eulerian Lagrangian (CEL) method becomes useful. The Coupled Eulerian Lagrangian method combines two different modeling strategies. […]
压电材料详解 | 它们是什么以及它们如何工作
Have you ever wondered why a quartz crystal can generate electricity just by being pressed? This isn’t magic—it’s the piezoelectric effect, a real physical phenomenon found in specific materials that convert mechanical stress into electrical energy and vice versa. These materials aren’t just theoretical curiosities. They’re widely used in everyday technologies, from medical ultrasound devices […]
Abaqus土壤建模 | 主要模型和应用
Do you think understanding soil behavior is easy?! Soil doesn’t act like a solid rock—it moves, settles, expands, and even turns to liquid during earthquakes. These behaviors make predicting soil response one of the most complex challenges in civil and geotechnical engineering. Understanding how soil reacts under various forces is key to building safe foundations, […]
平面应力与平面应变：它们是什么以及何时使用
If you’ve ever looked at a complex 3D model and thought, “There has to be a simpler way,” you’re not alone. That’s where the idea of plane stress vs plane strain comes in! These two clever shortcuts help engineers break down big problems into easier 2D ones. Not sure which one to use or why it matters? […]
应力-应变曲线详解 | 入门指南
What is stress strain curve? A stress strain curve is a graphical representation in material science that illustrates the relationship between stress (applied force per unit area) and strain (resulting deformation). Engineers analyze this curve to determine critical mechanical properties, including elasticity, yield strength, and ultimate tensile strength. Understanding how materials behave under mechanical load is [...] 韧性损伤：韧性材料失效机制的综合研究
Ductile damage is a gradual degradation of a material’s strength caused by the accumulation of tiny microscopic defects. It plays a critical role in metals and alloys, which are widely used for their strength, durability, and ductility across industries like automotive, aerospace, and construction. Understanding how ductile damage initiates, grows, and eventually leads to failure […]
结构优化：打造更智能、更轻便、更坚固的设计
Imagine designing a bridge that not only carries heavy traffic with ease but also uses 30% less material!! It costs less to build, weighs less to maintain, and leaves a smaller environmental footprint. This is the power of structural optimization. Structural optimization is the process of enhancing a design of a structure to meet specific […]
