Hydro-Mechanical Coupling of Cement-Based Slurry Grouting in Saturated Geomaterials

Mathematics, 2023
A mathematical model is proposed to simulate the fully hydro-mechanical coupling of two-phase cement-based slurry migration in saturated deformable geomaterials from microscopic to macroscopic scale.

Bézier base extended isogeometric numerical method for thermo elastic-plastic analysis of crack propagation in cracked plate under welding residual stress and thermal load

Mathematical Modelling and Analysis, 2022
A new procedure in the field of Bézier base extended isogeometric method (XIGA) has been introduced to analyze the effect of welding residual stress and thermal load on crack propagation rate and fatigue life.

Isogeometric treatment of large deformation contact and debonding problems with T-splines: a review

Curved and Layered Structures, 2015
Within a setting where the isogeometric analysis (IGA) has been successful at bringing two different research fields together, i.e. Computer Aided Design (CAD) and numerical analysis, T-spline IGA is applied in this work to frictionless contact and mode ...

Automatic Handling of C⁰-G⁰ Continuous Rational Bézier Elements Produced from T-Splines Through Bézier Extraction

Mathematics
This paper shows that at a certain time-point in the analysis procedure, the accuracy of T-spline based isogeometric analysis (IGA) may be substantially improved by increasing the multiplicity of the inner knots up to the polynomial degree. This task can
