Investigation of Spindle Rotation Rate Effects on the Mechanical Behavior of Friction Stir Welded Ti 4Al 2V Alloy

Nowadays, titanium and its alloys are widely utilized in various industrial parts in such areas as the petrochemical, medical, and automotive industries; However, due to structural considerations, the application is problematic in cases of joining. Ti 4Al 2V is a new type of titanium alloy, that in point of the structure is near to the α-series, which have many applications in critical conditions (moisture, steam, temperature, etc.).

A phase-field mixture theory of tumor growth

Our paper on the phase-field mixture theory of tumor growth is published in JMPS. The continuum model simulates significant mechano-chemo-biological features of avascular tumor growth in the various microenvironment, i.e., nutrient concentration and mechanical stress.

A unification of finite deformation J2 Von-Mises plasticity and quantitative dislocation mechanics

Rajat Arora       Amit Acharya

We present a framework which unifies classical phenomenological J2 and crystal plasticity theories with quantitative dislocation mechanics. The theory allows the computation of stress fields of arbitrary dislocation distributions and, coupled with minimally modified classical (J2 and crystal plasticity) models for the plastic strain rate of statistical dislocations, results in a versatile model of finite deformation mesoscale plasticity. We demonstrate some capabilities of the framework by solving two outstanding challenge problems in mesoscale plasticity: 1) recover the experimentally observed power-law scaling of stress-strain behavior in constrained simple shear of thin metallic films inferred from micropillar experiments which all strain gradient plasticity models overestimate and fail to predict; 2) predict the finite deformation stress and energy density fields of a sequence of dislocation distributions representing a progressively dense dislocation wall in a finite body, as might arise in the process of polygonization when viewed macroscopically, with one consequence being the demonstration of the inapplicability of current mathematical results based on $\Gamma$-convergence for this physically relevant situation. Our calculations in this case expose a possible 'phase transition'-like behavior for further theoretical study. We also provide a quantitative solution to the fundamental question of the volume change induced by dislocations in a finite deformation theory, as well as show the massive non-uniqueness in the solution for the (inverse) deformation map of a body inherent in a model of finite strain dislocation mechanics, when approached as a problem in classical finite elasticity.

Theoretical and Numerical Analysis of Anterior Cruciate Ligament Injury and its Prevention

Theory of physical aging from polymer science is, for the first time, introduced to understand ACL injury and its prevention. By analogy to physical aging of amorphous polymer materials, we think physical aging of two bundles of ACL will largely increase risk of ACL injury. Besides, physical aging will also build a heterogeneous stress and strain in ACL due to its natural anatomic structure, which is a large risk for athletes. The specific designed prevention programs for ACL injury such as plyometrics, strengthening and other neuromuscular training exercises [1] are believed to erase physical aging of ACL. ACL with less physical aging is less likely to get injured in sport activities. In this article, a virtual physical aging simulation is built to validate current hypothesis. Erasing physical aging of ACL may provide an accurate and quantitative way to prevent ACL injury.

Two-dimensional finite element analysis of elastic adhesive contact of a rough surface

Adhesive contact of a rigid flat surface with an elastic substrate having Weierstrass surface profile is numerically analyzed using the finite element method. In this work, we investigate the relationship between load and contact area spanning the limits of non-adhesive normal contact to adhesive contact for various substrate material properties, surface energy and roughness parameters. In the limit of non-adhesive normal contact, our results are consistent with published work.

PhD vacancy (4 years) on topology optimization of large 3D printed structures with functionally graded materials

Arc welding based additive manufacturing or WAAM techniques are attracting interest from the manufacturing industry because of their potential to fabricate large metal components with low cost and short production lead time. This process exists alongside other high deposition rate metal AM technologies such as powder and wire based DED. While these use either laser or an electron beam as energy source to melt a metal powder or wire, WAAM technologies melt metal wire using an electric arc.

PhD/postdoc vacancy (4 years) on computational mechanics of large wind turbine blades

Over the last years, UGent-MMS has developed the stand-alone BladeMesher software for generating finite element models of large wind turbine blades. The software reads in the material data and airfoil data of the wind turbine blade, and automatically constructs the geometry and finite element mesh for the blade. In a next step, the nodal and element information of the finite element mesh is written out to an input file for a commercial finite element solver (Abaqus in this case).

PhD vacancy (3 years) on experimental testing of thermoplastic automotive composites

Thermoplastic composites are gaining more and more interest in automotive, aerospace and sports applications, because of the short cycle times and recycling possibilities. Besides short fibre-reinforced thermoplastics, also continuous fibre-reinforced thermoplastic composites are being considered for load-carrying structures. However, their behaviour during manufacturing and during in-service use is very different from the traditional thermoset composites (typically epoxy-based).
