Results indicate that the presented experimental and numerical methods are efficient in studying the fracture mechanism of all-ceramic crowns.In this study the deformation in dentin and enamel resulting from the onset of dehydration was quantified using microscopic Digital Image Correlation (DIC).
Then specimens were placed on a precision mass scale with resolution of 0.1 mg to measure the mass loss under air convection in room temperature.The surface images were acquired with a microscopic imaging system and the strain of the specimens (dentin and enamel) in two orthogonal directions, i.e.It is indicated that the simulation that relies on multi-physics/multi-scale modeling has the potential to significantly reduce development costs and optimize the fabrication processes of LED The strain field of an edge dislocation in silicon was experimentally investigated.High-resolution transmission electron microscopy and geometric phase analysis were used to map the strain fields of the edge dislocation.The potential of this method is demonstrated by providing the phase reconstruction results of a phase grating and a single HEK293 cell.
The results showed good correspondence to the actual character of HEK293 cell prove the capability of digital micro-holography as a tool to monitor the dynamic transfection process of the living HEK 293 cells.
parallel and perpendicular to the dentin tubules and enamel prisms were analyzed.
Results show that both tissues underwent shrinkage with water loss in the two orthogonal directions and regardless of age.
Meanwhile numerical simulation was also carried out to support the experiments.
Stress distributions in individual layer and interface were presented.
The magnitude of strain within the enamel is lower than that within the dentin.
