| Title: | Comparação de elementos finitos tridimensionais |
| Author(s)/Inventor(s): | Matos, Henrique de Carvalho |
| Advisor: | Carneiro, Fernando Luiz Lobo Barboza |
| Abstract: | Analisa elementos finitos tridimensionais. Estão estudados os elementos isoparamétricos ZIB-8 e ZIB-20, o elemento tetraedro TET-4, e feito um programa automático com o qual se analisou os elementos hexaédricos ZIB-8 e duas composições de 12 e 24 tetraedros. A apresentação do trabalho está orientada no sentido da preparação de um programa automático que tentasse resolver estruturas tridimensionais de porte médio de maneira satisfatória. A programação do elemento ZIB-20, hexaedro de 8 nós nos vértices e 12 no meio dos lados, apesar de iniciada foi interrompida devido ao fato de se dispor de um computador de memória insuficiente, de ser difícil a entrada de dados ou uma geração automática, e aumentar demasiadamente o tempo de computação. |
| Abstract: | Analyzed are finite three-dimensional elements. The elements studied are the hexahedron isoparametric ZIB-8 and ZIB-20, the tetrahedron TET-4, and there is formed an automatic program where the element ZIB-8 and two compositions of 12 and 24 tetrahedron, are analyzed. The presentation of the work id orientated for preparation of a automatic program to have the ability to resolve three-dimensional structures of middle proportions in a satisfactory manner. The programming of the element ZIB-20, hexahedron of 8 points in vertexs and 12 points in the middle of the sides, was interrupted in the beginning because of the fact that the memory of the computer was insufficient, making it difficult for the input of data or the automatic generation, and increased greatly the time of computation. |
