如何把不分離no separation和法向接觸normal contact中的tabular相結(jié)合使用? 已有1人參與
|
|
接觸當(dāng)中的法向接觸normal contact有tabular這個(gè)類(lèi)型。在默認(rèn)狀態(tài)下只能輸入壓應(yīng)力和對(duì)應(yīng)的侵徹深度。 但是我在閱讀abaqus官方說(shuō)明手冊(cè)時(shí)候看到有這樣的用法,接下來(lái)是原文 “Softened” contact with the no separation relationship in Abaqus/Explicit In Abaqus/Explicit if a softened contact relationship is specified with the no separation relationship, the pressure-overclosure relationship will include tensile behavior. The exponential relationship cannot be used with no separation behavior. For the tabular relationship, a point must be specified on the zero pressure axis, and the slope will continue into the tensile regime following the same slope as the first two data points (see Figure 33.1.2–7). The linear relationship will have a linear tensile pressure-overclosure relationship with the same slope that is used for the compressive behavior. 這段話我覺(jué)得意思就是在使用了no separation的情況下,法向接觸tabular就可以不僅提供壓應(yīng)力和侵徹深度,還可以提供拉應(yīng)力和分離距離。 但是在軟件當(dāng)中沒(méi)有把no separation和tabular法向接觸結(jié)合起來(lái)的選項(xiàng),因此我應(yīng)該怎么操作? |

那官方手冊(cè)當(dāng)中這段提到的應(yīng)該怎么解釋?zhuān)縯abular法向接觸又是怎么提供的拉應(yīng)力?因?yàn)榉ㄏ蚪佑|默認(rèn)描述的是壓應(yīng)力。 發(fā)自小木蟲(chóng)Android客戶端 |
