对于LS DYNA中的define curve 关键词,仿真对象为三个筒型结构, 目的是使三个筒下沉贯入时整体倾斜角度能够通过修改载荷进行控制,当你通过简单重启动改变载荷的输入值(其他都不改变)并应用到define curve中,但仿真计算时,施加的载荷在计算中并没有改变,整体倾斜角度也没有改变,请问各位大佬是哪里出现了问题 使用hyper...
在*DEFINE_CURVE的注解里,第一句是: In the definition of Load Curves used in the constitutive models, reasonable spacing of the points should always be observed, i.e., never set a single point off to a value approaching infinity. LS-DYNA uses internally discretized curves to improve efficiency ...
curve定义的内容可以是应力应变，可以是随时间变化的量。
Ques: Which of the following is an open curve?Choices:A. circle B. ellipse C. parabola D. none of the above Correct Answer: CSolution:Step 1: In an open curve starting and end points are different. Step 2: Here, parabola has different end points. Step 3: So, parabola is an open ...

Define curve profiles to specify how scope assignment costs, quantities, and hours spread over the duration of an activity; resource or role hours spread over the duration of an activity; and budget quantities over budget durations. There are some default curve profiles defined in the application....
Describe the long-run Philips curve. Provide a concise explanation of the Expectations-augmented Phillips Curve. Explain what it means to say that the Phillips curve presents policymakers with a menu of choices. How does the appearance of a short-run Phillips curve differ from that of th...
When using the Input grapher, you use points to define the sectors of the curve . Add and delete points Each sector of the graph is defined by two points. To add a point: Double-click the appropriate position in the graph, or right-click at the appropriate position, and then ...
