This paper introduces an unconventional constitutive model for soils which deals with a unified thermo-mechanical modelling for unsaturated soils. The relevant temperature and suction effects are studied in light of elasto-plasticity. A generalized effecti ...
Soil is a particulate material that may undergo irreversible strain as the relative positions of the constituent particles change. That irreversible behaviour may be induced not only by an external stress variation but also by temperature or suction change ...
This paper addresses a new, unified thermo-mechanical constitutive model for unsaturated soils through a coupled study. In the context of elasto-plasticity and the critical state theory, the model uses the concepts of multi-mechanism and bounding surface t ...
This paper compares different models currently used to calculate the shear strength of unreinforced masonry (URM) walls retrofitted using fiber reinforced polymers (URM-FRP). The shear strengths of six recently tested URM-FRP walls were compared to shear s ...
One of the primary objectives of this work is to better understand the frictional behavior of joints under shear loads, including the creation of damage zones. Discontinuities have an important influence on the deformational behavior of rock systems. The c ...
Since decades traditional friction welding methods are applied industrially to metal and thermoplastic synthetics. Research showed that for different applications this method is promising for wood too. The process does not necessitate any additional materi ...
A method to predict the strength of adhesively bonded single and double lap joints from pultruded GFRP composite adherends subjected to quasi-static axial tensile loading is presented. The method is based on a quadratic through- thickness shear-tensile int ...
Physical properties including the equation of state, elasticity, and shear strength of pyrite have been measured by a series of X-ray diffraction in diamond-anvil cells at pressures up to 50 GPa. A Birch-Murnaghan equation of state fit to the quasi hydrost ...
The state-of-the-art report presented herein is aimed at documenting, to the largest extent possible, some of the recent advances in laboratory testing of unsaturated soils for stress-strain-strength-stiffness characterization under suction-controlled isot ...
An experimental and theoretical investigation of the shear strength of reinforced concrete slabs without shear reinforcement is under way at the Ecole Polytechnique Fédérale de Lausanne. The first part of the program consists of 6 tests on two large scale ...
