In this paper, layerwise theory (LT) along with the first, second and third-order shear deformation theories (FSDT, SSDT and TSDT) are used to determine the stress distribution in a simply supported square sandwich plate subjected to a uniformly distributed load. Two functionally graded (FG) face sheets encapsulate an elastomeric core while two epoxy adhesive layers adhere the core to the face ...

  Abstract   Recovery and recrystallization phenomena and effects of microalloying elements on these phenomena are of great importance in designing thermomechanical processes of microalloyed steels. Thus, understanding and modeling of microstructure evolution during hot deformation leads to optimize the processing conditions and to improve the product properties.   In this study, finite element...

Methods: Suppose Ø:S1->S2 is a map from the surface S1 to the surface S2, we define the derivative map of Ø is the linear map between the tangent spaces, dØ:TM(p)->TM(Ø(p)), induced by the map. Let J be the derivative map and define the deformation tensor as S=(JTJ)1/2. Instead of analyzing shape change based on the eigenvalues of the deformation tensor, we consider a new family of metrics, the...

DeepWarp is an efficient and highly re-usable deep neural network (DNN) based nonlinear deformable simulation framework. Unlike other deep learning applications such as image recognition, where different inputs have a uniform and consistent format (e.g. an array of all the pixels in an image), the input for deformable simulation is quite variable, high-dimensional, and parametrization-unfriendl...

Fast and realistic soft-tissue deformation is an important feature for medical simulation environments. In this work we present a direct deformation approach for volumetric datasets which is completely performed on the GPU. It takes on the one hand advantage of a GPU's computing power; on the other hand deformation is easily combined with hardware-supported rendering. Our deformation technique ...

Optics-based tracking of civil structures is not new, due to historical application in surveying, but automated applications capable of tracking at rates that capture dynamic effects are now a hot research topic in structural health monitoring. Recent innovations show promise of true non-contacting monitoring capability avoiding the need for physically attached sensor arrays. The paper reviews ...

This paper presents a novel deformation system for video objects. The system is designed to minimize the amount of user interaction, while providing flexible and precise user control. It has a keyframe-based user interface. The user only needs to manipulate the video object at some keyframes. Our algorithm will smoothly propagate the editing result from the keyframes to the rest frames and auto...

Most 3D character editing tools are complex and non-intuitive. It takes lot of skill and labor from the artists to create even a draft 3D humanoid model. This paper proposes an intuitive 2D sketch-driven drafting tool that allows users to quickly shape and proportion existing detailed 3D models. We leverage on our existing vector shape representation to describe character bodypart segments as a...

This paper presents a method for effectively modeling the outer surfaces of inlay/onlay prostheses restoring teeth that are partially destroyed. We exploit 3D mesh deformation techniques: direct manipulation free-form deformation (DMFFD) [9] and multiple wires deformation (MWD) [10] with three kinds of information: standard teeth models, scanned mesh data from the plaster cast of a patient's to...
