冰球失效准则详解 | 三种失效模式详解 + Abaqus 仿真
Composites have been widely used for years due to their unique properties, but their complexity makes failure analysis challenging. Engineers rely on various failure criteria like Hashin, Tsai-Wu, and Tsai-Hill to guide their designs. However, the Puck Failure Criterion offers a more refined approach by not only distinguishing between fiber and matrix failures but also […]
Abaqus UEL 和 VUEL 子例程：简介、变量、Abaqus UEL 示例
Have you ever thought about having custom elements in Abaqus? Abaqus provides many built-in elements, but sometimes they are not enough for specialized simulations. If you need to model complex materials, unique geometries, or advanced physical behaviors, the default options may not work. This is where the Abaqus UEL (User ELement) subroutine becomes useful. The […]
Abaqus焊接仿真完全指南：基本方法和理论详解
Abaqus welding simulation is crucial when predicting the impact of welding on materials. It helps engineers understand heat effects, deformation, material distortion, and residual stresses. This is particularly useful in complex welding situations, where traditional methods may not provide accurate results. Abaqus allows for a detailed analysis of thermal distribution and material behavior, making it […]
Abaqus DFLUX 和 VDFLUX 免费教程：分步指南
Did you know that in the real world, heat transfer and mass diffusion often occur unevenly? From electronic devices where some parts heat up faster to industrial processes like welding with highly localized heat sources, nonuniform fluxes play a critical role in accurately modeling these phenomena. The DFLUX and VDFLUX subroutines in Abaqus allow engineers […]
模态分析 | 固有频率与模态 | 基础知识和 Abaqus 教程
Modal analysis is a way to find out how something vibrates. Every object has its own natural way of shaking when it’s pushed or disturbed. Modal analysis helps engineers figure out those natural vibration patterns so they can design things that don’t fail or shake too much when forces act on them. When the vibration of […]
Abaqus UAMP (VUAMP) 子程序入门指南 | Abaqus 用户自定义振幅简介
In the world of finite element analysis, accurately representing how loads change over time is crucial. This is where load amplitude definition comes in. Abaqus, offers various predefined amplitudes for common loading scenarios. But what if you need to simulate a more complex load pattern? Here’s where UAMP Abaqus (VUAMP Abaqus) and Abaqus user-defined amplitudes […]
什么是 Abaqus 混合单元？ | Abaqus 常见单元错误
Did you know that Abaqus hybrid elements can effectively handle incompressible materials? Hybrid elements are designed to overcome the limitations of traditional displacement-based elements by introducing an additional degree of freedom, pressure, which independently represents the volumetric component of stress. This feature is crucial for accurately simulating incompressible or nearly incompressible materials, such as rubber [...] Abaqus中的损伤和断裂力学分析
Fracture & Damage Mechanics In simple terms, fracture mechanics is concerned with understanding how and why materials fracture, and predicting the conditions under which failure is likely to occur. It involves studying the progression of cracks and other defects in materials, and how they respond to different types of loading, such as tension, compression, and […]
