Transform Faults, Fracture Zones, and the Kinematics of Horizontal Thermal Contraction of Oceanic Lithosphere
… Gordon [2009] advance the theory of horizontal thermal contraction of oceanic lithosphere as the ultimate test of plate rigidity and predict that relative intraplate velocities due to horizontal thermal contraction within the oceanic lithosphere of a tectonic plate can be as high as 3 – 10 mm …

Comparison of oil and intensive quenching via coupled thermal, transformation, and mechanical modeling
… austenitic core. As the core cooled and thermally contracted, the shell was pulled inward to maintain coherency between the shell and the core. When the core austenite transforms, the volume expansion was insufficient to overcome the thermal contraction resulting in large compressive …

A biomechanical investigation of the structure--function relationships in the human tongue
… The results demonstrated that synergistic co-contraction between various muscle populations produced the necessary deformations in global tongue shape. In order to delineate specific muscular contributions to sagittal bending, the tongue was modeled by a thermal bimetal strip analog wherein …

Structural, vibrational and thermodynamic properties of carbon allotropes from first-principles : diamond, graphite, and nanotubes
… data. The vibrational free energy and the thermal expansion, the temperature dependence of the elastic moduli and the specific heat are calculated using the quasi-harmonic approximation. Graphite shows a distinctive in-plane negative thermal-expansion coefficient that reaches its lowest …

Development of LTTW consumables for the enhancement of mechanical properties and residual stress management in thin steel welded joints
… martensitic transformation compensates for the thermal contraction during cooling. In this work, a LTTW wire, EH200B, was designed for arc welding of DP980 AHSS thin plates. Its composition was tailored for electrode weldability optimization. Effects of the LTTW wire on weld microstructure, …

Continental Deformation: Collisional Orogenesis to Passive Margin Processes
… Cenozoic (34 Ma – 10 ka) which correlate with thermal contraction and density driven subsidence, asymmetric basin filling, and flexure beneath a rapidly prograding shelf margin wedge, respectively. My results show that GoM subsidence can be adequately explained without the influence of the …

Dimensional Stability and Properties of Thermoplastics Reinforced with Particulate and Fiber Fillers
… is primarily attributed to residual thermal stresses associated with shrinkage and thermal contraction of the parts. Therefore, it is assumed that flow-induced stresses generated during mold filling do not play a significant role in the warpage. The warpage of PP composites reinforced …

Recrystallisation in Single Crystal Nickel-Based Superalloys
… Ni-based superalloys arise from differences in thermal contraction between the metal and ceramic mould-and-core. If deformation is above a critical limit, subsequent solution heat treatment of the alloy causes recrystallisation. Crack nucleation and propagation is preferred at the …

Shape distortion and air gap formation during continuous casting.
… mould wall by the metallostatic pressure. The thermal contraction of the neutral axis "filament" along the whole shell determines the amount of room which is available for the detached corner portion to distort, and thus also the size of the detached lengths of shell. The mechanical equilibrium …

Atomic structures of carbon nanomaterials studied by coherent electron diffraction
… heating experiment of the same MWCNT shows large thermal contractions for all the walls of the MWCNT, and the coefficient of radial thermal contraction has strong diameter dependence. Electron diffraction evidences also suggest that the CNTs deviate from the ideal smooth tubular structure. Using a …

Epitaxial graphene and cluster lattices on Iridium(111)
… TPG and CVD growth. Due to the difference in thermal contraction of graphene and Ir, compressive strain builds up during cooling down to room temperature. This strain is relieved by the formation of wrinkles at a cool down of approx. 400K. The formation of wrinkles and the accompanying strain …

Dynamic distributed monitoring of masonry railway bridges
… a larger magnitude response – potentially due to thermal contraction of the masonry causing existing cracks throughout the bridge to open, and thus increasing the potential for movements to occur under applied loads.
