Abstract

Dear Mechanicians,

You are cordially invited to submit your abstract (text 400 words) to our Symposium on Recent Advances in Mechanical Metamaterials (symposium 352) as part of the 18th U.S. National Congress for Theoretical and Applied Mechanics that will be hosted by Northwestern University at the Hyatt Regency O’Hare from June 5 to June 9, 2018.

Abstract submission is open until November 10, 2017

The expansion behavior of cellular materials is especially attractive for potential applications such as design and development of bio-inspired adaptive materials since most of biological materials have a cellular microstructure at least at one of their hierarchical levels. Wood, bone, bamboo, ice plant and honeybee combs are examples of such natural materials.

Dear All,

 I think that many students are looking for some tutorials about writing a UMAT in ABAQUS.

You can find a comprehensive tutorial for elastic problems.
