| Abstract: | The paper is concentrated on stress strength factors of model I fracture at crack tip of Fraxinus mandshurica Rupr.wood Firstly,by NASTRAN software of the United States MSC company,the data of stresses are figured out,and then,by GRAFTOOL software dealing with the data,the distribution diagram of stress factors at crack tip of Fraxinus mandshurica Rupr. Wood are drawn. |
