An assessment of the true stress-true strain relationship has been done by means of tensile and small ball punch tests on austenitic and tempered martensitic steel at room temperature. A finite element model was developed and validated to calculate the for ...
The possibility of decreasing ultimate tensile strength associated with increasing fiber/matrix interfacial sliding is investigated in ceramic-matrix composites. An axisymmetric finite-element model is used to calculate axial fiber stresses versus radial p ...
Ultra-High Performance Fibre-Reinforced Concretes (UHPFRC) have high mechanical strengths (fU,c > 150 MPa, fU,t > 6 MPa) and exhibit quasi-strain hardening in tension. Their very low permeability prevents the ingress of detrimental substances. In composite ...
Estimation of the stress distribution in the solder or glue joint between a cantilever and its base, and of the corresponding bending stress distribution in the cantilever. This reports details results of modelling of the stresses in the solder or glue joi ...
We have examined the micromechanical behavior of in situ formed metallic glass composites by performing in situ high-energy synchrotron X-ray scattering during uniaxial compression. The load partitioning between the amorphous matrix and the reinforcing par ...
The tensile behaviour of composites produced by infiltrating ceramic particle beds with high purity (99.99%) At is studied as a function of reinforcement size and chemistry (Al2O3 and B4C). The yield stress is higher in composites containing B4C particles, ...
A new simple model for predicting the uniaxial stress-strain behavior of a unidirectional ceramic matrix composite. including stochastic matrix crack evolution, stochastic fiber damage and ultimate failure, is presented. The model demonstrates an important ...
It is shown that extrusion of "FORMGRIP" precursor material prior to baking leads to accelerated foaming and finer, more uniform cell structures. This effect is correlated with microstructural observations made on the precursor materials and on the foams, ...
We present oblique powder blasting as a three-dimensional micromachining technology for brittle materials. Powder blasting is a microfabrication process, based on the use of a pressurised air beam containing eroding Al2O3 particles. By varying the angle of ...
