Matlab code for intermetalic layer thickness

Submitted by chironjeet.chaki on

I need a matlab code for measuring intermetallic layer thickness of Cu-Sn binary alloy during soldering.

I will use the result for Characterization of intermetallic layer and also time based analysis of mechanical failure.

I would be really grateful to the person who can help me over this issue.

 

Thanks a lot in advance.

Predicting fracture energies and crack-tip fields of soft tough materials

Submitted by Teng zhang on

Soft materials including elastomers and gels are pervasive in biological systems and technological applications. Whereas it is known that intrinsic fracture energies of soft materials are relatively low, how the intrinsic fracture energy cooperates with mechanical dissipation in process zone to give high fracture toughness of soft materials is not well understood. In addition, it is still challenging to predict fracture energies and crack-tip strain fields of soft tough materials.

Additive Manufacturing (3D printing) lab at TU Delft

Submitted by azadpoor on

After several years of research in the area of additive manufacturing, biofabrication, and additively manufactured biomaterials and implants, I finally put up the first version of the website of my lab. I will gradually improve the website, but there is already links to all publications coming out of my lab in the general area of AM.

 

Simpleware case study: 3D FE Model of the Diabetic Neuropathic Foot

Submitted by Simpleware on

Diabetic foot represents a complication of diabetes that can lead to foot ulcers and other serious conditions. 3D Finite Element (FE) analysis enables dynamic characterisation of different loads within the foot.

This study developed a subject-specific 3D FE model of a diabetic neuropathic and a healthy subject’s foot from MRI data. Experimental analysis of the biomechanics of the foot was combined with FE simulations of foot models generated in Simpleware software.

Constructive and Destructive Interplay between Piezoelectricity and Flexoelectricity in Flexural Sensors and Actuators

Submitted by Amir Abdollahi on

Flexoelectricity is an electromechanical effect coupling polarization to strain gradients. It fundamentally differs from piezoelectricity because of its size-dependence and symmetry. Flexoelectricity is generally perceived as a small effect noticeable only at the nanoscale. Since ferroelectric ceramics have a particularly high flexoelectric coefficient, however, it may play a significant role as piezoelectric transducers shrink to the sub-micrometer scale. We examine this issue with a continuum model self-consistently treating piezo- and flexoelectricity.
