構造解析シミュレーションは、構造に対する重量と張力の影響を研究するためのものです。応力や振動に対してコンポーネントや製品アセンブリがどのように反応するかを理解することは、どの業界でも非常に重要です。しかし製品と材料の複雑化が進むにつれて、エンジニアには線形静解析だけにとどまらないツールが必要になってきました。
Simcenterは、単一のユーザー環境内で幅広い用途のシミュレーションを行うために必要な構造解析ソフトウェアを提供します。線形静解析、疲労解析、非線形解析に別々のツールを用意する必要はありません。その結果、エンジニアリング部門は構造解析ツールを整理統合でき、ユーザーは1種類のユーザー・インターフェースを習得するだけですみます。

Finite element analysis (FEA) is the technological and mathematical foundation for simulating structural performance. FEA is a well-established methodology to aid the engineering design and analysis of many kinds of products.
Linear structural analysis is a method used to determine how a structure behaves under load, assuming a linear elastic material and small deformations. This is the most common type of structural analysis performed today.
Nonlinear structural analysis is used to account for changes in a structure's geometry, material properties, and stiffness when subjected to loads, where the relationship between forces and displacement is not linear.

Linear analysis is used to solve static problems, such as determining if a structure will fail under a prescribed load. This analysis is particularly useful for studying structures under static loads, where the loads are applied slowly and remain constant over time.
With the Simcenter Nastran solver, you can simulate both transient and harmonic excitations and use its damping models to choose between direct or forced response.

Normal modes analysis helps you to determine the natural frequencies and corresponding mode shapes of a structure. This helps you understand the dynamic behavior of your design and identify potential resonance problems.
Understanding your model's dynamic behavior through modes and test measurements can help you achieve an accurate and efficient solution. Thanks to the rapid analysis capabilities of RDMODES, Simcenter Nastran can generate modes for large systems with numerous modes
Simcenter can help you predict the load at which a structure will buckle or undergo a sudden change in shape under compressive loads. This helps you identify potential stability issues and optimize designs for slender or thin-walled structures.
Multistep nonlinear analysis is an advanced solution that provides comprehensive capabilities for geometric nonlinear, contact, plasticity, creep, hyperelasticity and other material behaviors. The multistep solution allows users to set up sequential subcases for preload, nonlinear statics, nonlinear transient, modal, buckling, post
buckling, harmonic modes and frequency response.
Simulate components made with nonlinear material properties, such as:
hyperelasticity models (Mooney-Rivlin, Ogden, hyperfoam, Mullins effect, damping with Prony series), elasto-plastic (Von Mises yield criterion, isotropic hardening, kinematic hardening, mixed hardening), thermal elastoplastic, creep, and combined creep and elastoplastic.
Simulate designs that will have large deformations or large strains. You can also simulate snap-through analysis (post-buckling) or follower forces.
Simcenter lets you simulate nonlinear models that will have contact with itself or other components.
Aeroelastic flutter is a critical phenomenon where an unstable structural oscillation occurs in an airframe caused by resonance frequencies coming from the airstream around the moving aircraft. Engineers need to understand when and where flutter will be a problem. Simcenter includes the tools you need to predict and avoid unwanted flutter, accurately.
