The only thing similar is the inset command, followed by a couple other operations. In order to create a similar effect to Wings Intrude command, you'd have to perform an inset by individual polygons, or by region, then remove (delete) the inset faces, and apply a solidify modifier to the object to make a solid, manifold surface. Wings is a "solid", or manifold, modeling application, so the Intrude command obeys the laws of manifold modeling by essentially doing several types of operations one tool. Blender, while having more overall versatility, does not always try to maintain manifold surfaces in its modeling operations, and would require a combination of operations to perform that same action behavior.
