Questions related to Engineering Drawing
Below you can find equetion which express flow curve which describes the plastic deformation behavior of a material in a uniaxial tensile (or compression) test. I looking for books, articles which gives me information how values of C and n depends on geometry (eg. diamater and wallthicknes of drawn tube) as well as initial mechanical properties, before material work hardening. Do wires and rods of the same material but with different dimensions have a different form of the flow-curve, or does it depend only on the initial properties of the material?
There are quite a few good plotting software and packages available to draw professional graphs and visualize data. Some of them are paid, some are free; some are language-based, some are independent. Which one do you prefer and why?
Formally, a computer program should be able to scan such an image, perform image processing or any specific treatment on it and produce the followings.
1) The info about multiple geometrical shapes stacked together in front/side and top views in the image.
2) The correlation between the two views as some shapes (or a part of a shape) are hidden in one view but their projections are seen in the other view.
3) The relationship among shapes such as the orientation of a shape w.r.t. to each other.
4) The info about dimensions normally written in text besides arrows.
5) The info about arrows, single-headed, double-headed, straight, slanted, etc.
Or I should apply the controllable canonical form to the plant and put the positive refeeding ?
Does the controllable canonical transformation serving exactly?
Thank you very much.
Drawing in general requires some imagination and many students are having difficulty in acquiring this skill. I think the complexity of this subject could be modeled through cognitive science findings. For example, we may take an advantage of the findings of mental images and develop a curriculum that mitigate this complexity.
Is there any change in knot vectors between uniform & nonuniform Bspline? What are the equations used to calculate Knot vectors in both of these cases?
Building information modeling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of a facility. The resulting building information models become shared knowledge resources to support decision-making about a facility from earliest conceptual stages, through design and construction, through its operational life and eventual demolition.
