Abstract(J)構造部材の曲げや座屈変形を対象にして,Isogeometric解析(IGA)の性能評価を実施する.自動車の衝突解析等においては,変形挙動はもちろんのこと加速度や速度などのパルスの実現象との整合性がその精度確保のために重要である.これらの整合性を確保するためには,構造部材の曲げや座屈などの忠実な再現が必要である.本研究では,IGAによってモデル化された構造部材の曲げと座屈解析を実施し,有限要素解析と比較することでその性能を評価する.

Translation

Abstract(E)We evaluate performance of Isogeometric analysis (IGA) for bending and buckling deformation of structural members. In automobile crash analysis, ensuring the accuracy of the pulse such as acceleration and velocity, as well as the deformation behavior is important. For the above this consistency, accurate reproducing the bending and buckling of structural members are indispensable. In this study, we compute bending and buckling of structural members are modeled with IGA and validate its performance by comparing the results with finite element analysis.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
