laboratory with scientists


It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.

Biomedical Engineering

The course is intended as an introduction to the field of Biomedical Engineering. In this context, the class familiarizes students with basic biological concepts, biological materials (cells, proteins, tissues, blood etc.) and how these interact with each-other. The interplay between physical forces and cell function/evolution is analyzed towards an understanding of mechanotransduction and the underlaying phenomena (Bio-signaling and sensing). Medical devices and implants and fundamental aspects thereof: Biomaterials, Biocompatibility, Bio degeneration, Bio-Mimetics and Nanomaterials.

Strength of Materials

The course content is structured around 6 main pillars: Axial loading: Safety Factor, Hooke’s law, Modulus of Elasticity, Elastic vs. Plastic behaviour, Static indeterminacy, Thermal stresses, Poisson’s ratio, Hooke’s law (generalized), Torsion: Stress, strain, angle of twist in elastic range, statically indeterminate shafts, design of transmission shafts, stress concentrations. Pure Bending: Deformations in symmetric member, strain due to bending, bending of members made of several materials, stress concentrations, asymmetric bending, general case of eccentric axial loading. Design and analysis of beams: N,Q,M diagrams, determination of the shearing stress in common or complex types of beams, shear stresses in thin-walled members. Stress–Strain Transformations: Plane stress transformation, principal stresses, maximum shear stress, Mohr’s Circle for plane stress and general Three-Dimensional analysis of stress and strain. Deflection of beams: Deformation of a beam under transverse loading, equation of the elastic curve, determination of the elastic curve from the load distribution, method of superposition, moment–area theorems.
