3D Printing of cylindrical shells with varied stiffness

Submitted by Nan Hu on

Hi, all,

I'm planning to print a series of cylindrical shells with different material patches on shell surface. The size is about 100 mm in length, 80 mm in diameter and 0.5 mm in shell thickness. The shell was designed with varied stiffness by using two different material properties. The 3D assembly has been created with two groups such that it is easy to select one group for a specific material. I wonder did any of you try some commercial 3D printing companies or providers who can fabricate similar structure with varied stiffness and afforable cost. Let me know. Thanks!

Microstructurally based cross-slip mechanisms and their effects on dislocation microstructure evolution in fcc crystals

Submitted by ahmed.hussein on

Three newly identified cross-slip mechanisms from atomistic simulations of fcc crystals, namely surface, bulk and intersection cross-slip types, were hierarchically informed into discrete dislocation dynamics simulations. The influence of each cross-slip type on the evolution of the dislocation microstructure in face-centered cubic microcrystals having different crystal sizes and initial dislocation densities was investigated.

Postdoc Positions at Brown University (Solid Mechanics), Providence RI

Submitted by Allan F Bower on

The solid mechanics program at Brown has two openings for postdoctoral research associates in the areas of computational modeling of battery electrode materials, and computational design of advanced high-strength steels.   One position is available immediately; the other towards the end of August.   Both projects will have opportunities to work closely with experimental and industrial collaborators.

EML is born

Submitted by K Jimmy Hsia on

Dear Friends,
Let me assure you that we (the editorial team) are just as anxious as you are to see what kind of papers are published by EML, with similar anticipation as one looks at a new born baby for the first time.  Does the baby girl have big eyes like her mother? Or does the baby boy have little hair on his head like his father? Or the baby is just different, different from all other children, and beautifully so.

Optical microscope for three-dimensional surface displacement and shape measurements at the microscale

Submitted by Shuman_Xia on

We report a novel optical microscope for full-field, noncontact measurements of three-dimensional (3D) surface deformation and topography at the microscale. The microscope system is based on a seamless integration of the diffraction-assisted image correlation (DAIC) method with fluorescent microscopy. We experimentally demonstrate the microscope’s capability for 3D measurements with submicrometer spatial resolution and subpixel measurement accuracy.
