The paper is dedicated to the modeling of elasticity problem for a textile structure. made long and thin fibers, crossing each other in periodic pattern, forming woven canvas square domain. partially clamped. fibers cannot penetrate but can slide with respect in-plane directions. sliding bounded by contact function, which chosen loose. partial clamp loose lead domain partitioning, different exp...

OBJECTIVE To determine if there is an association between cervical strain, evaluated using ultrasound elastography, and spontaneous preterm delivery (sPTD) <37 weeks of gestation. METHODS One hundred and eighty nine (189) women at 16-24 weeks of gestation were evaluated. Ultrasound elastography was used to estimate cervical strain in three anatomical planes: one mid-sagittal in the same plane...

The dual formulation for linear elasticity, in contrast to the primal formulation, is not affected by locking, as it based on stresses main unknowns. Thus quite attractive nearly incompressible and materials. Discretization with mixed finite elements will lead to—possibly large—linear saddle point systems. Whereas efficient multigrid methods exist solving problems plane elasticity materials, we...

On the basis of the theory of three-dimensional elasticity, this paper presents a state space finite element solution for the stresses in cross-ply laminates subjected to combined transverse and in-plane loads. The state space formulation is introduced to solve for through-thickness stress distributions, while the traditional finite elements are used to approximate in-plane variations of the st...
