Reduced integration

Reduced integration

Reduced integration

(OP)
How the stresses are recovered to nodes from reduced integration?
Element quad4, one gauss point in the center of element.

RE: Reduced integration

They're extrapolated according to the element shape function and then averaged to give a single value.

The same procedure is used for fully-integrated elements

RE: Reduced integration

(OP)
Dave442 I agree for the stress recovery for 4 Gauss point.
But I can not imagine inter/extrapolation from one Gauss point.
Is is not that the stresses at nodes of element are the same as stress at one/centre Gauss point?

RE: Reduced integration

For an element with one integration point the stresses at the nodes and integration points are the same.

These elements are sometimes called constant stress/strain elements.

Nodal values may still get averaged to produce a single value though.

Research Report: The Next Product You Design Might Be a Service Thanks to the IoT
For this report, the editors of engineering.com interviewed companies on the leading edge of implementing products as a service with a view to describing and categorizing the types of products that can be delivered as a service and the technologies that make it possible—one company in high-tech manufacturing, another who helps ensure access to clean water in developing nations, and a third in the mass transportation industry.
