A recently published paper  "Evaluating the macroscopic yield behaviour of trabecular bone using a nonlinear homogenisation approach" links the micromechanics of bone to its macroscopic behaviour. The paper may be of interest to colleagues on this forum. The abstract is provided below.

Fracto-emission in lanthanum-based metallic glass microwires under quasi-static tensile loading

Fracture mechanics; non-linear stress-strain behavior; metallic glass; microwire; in situ SEM testing; nanomechanics; fracto-emission

Plastic deformation in metallic glasses is highly localized and often associated with shear banding, which may cause momentary release of heat upon fracture. Here, we report an explosive fracture phenomenon associated with momentary (∼10 ms) light emission (flash) in Lanthanum-based (LaAlNi) metallic glass microwires (dia. ∼50 μm) under quasi-static tensile loading.

Cohesive zone model

Hi, 

I'm actually working on numerical modeling of  damage in adhesively bonded joints.  I found three basic approaches for it in litterature 

_Continuum approcha

_local approach

_Hybrid CZM_ XFEM approach

I'm trying a model on local approach, but i faced a problem which consits of overlapping continuum adhesive layer and adherends elements when cohesive elements get fully damaged

I need a suggenstion on how to hadnle this problem.

Thanks in advance

SES Annual Meeting

Dear Colleagues,

The 53rd Annual Technical Meeting of the Society of Engineering Science will be hosted  by the University of Maryland (UMD) during 2-5 October 2016 (note the new conference date). As part of this meeting, we are organizing a symposium to address recent experimental, computational, theoretical, and manufacturing advances on the mechanics and physics of soft materials. Topics of particular interest include:
