In this paper, the bearing capacity of rigid pile composite ground under vertical loads and the law of variation of pile-soil bearing ratio among pile-soil interaction are calculated and analyzed on the basis of discrete element method of the deformable body model, which describes the bearing mechanism of pile-soil interaction of rigid pile composite ground.
To solve the problems of large displacement and discontinuousness in rock and soil engineering, a element model for deformable bodies was built according to the fundamental principle of dynamics of deformable bodies and discrete element method.
The dissertation mostly addressed the technology of garment simulation in virtual human animation, including virtual human body modelling, character animation, physically based cloth simulation, collision detection and response for deformable objects.
The first objective of the present thesisis therefore to establish a second order hydroelasticity theory and the correspondingnumerical method for investigating the effect of the above mentioned second order waveforces on the structural behavior of the floating body.
It is difficult to implement the face recognition mechanism using computers for several reasons. First, human face is a deformable object composed of complex 3D curve surfaces, which is hard to be represented in form of mathematics.
The analytically established relations are suitable for use in several mechanical and engineering applications as, for instance, in the problem of heat and electric current conduction through a contact between solid deformable bodies.
An experimental technique for estimating the conditions acting on the contact surfaces of mutually deformable bodies as applied to geomechanical measurements is considered.
The topic discussed plays an important role in dealing with questions about the kinematics of deformable bodies when Lagrangian measures for finite deformations are assumed and Cauchy's polar-decomposition theorem is applied.
By using the description method of comoving coordinates and the geometric field theory developed in the previous part of this paper (Acta Mechanica Sinica (2) 1979, 107-117), the fundamental equations and the energy principles for finite polar elasticity have been established. These make improvements to Fraeijs de Veubeke's formulation (1972) of new variational principle which based on polar decomposition theorem. Engineering applications are shown for large deflection of beam and Koiter's solution (1973)...
The theory of coupled fields in magneto-elasticity is surveyed.The twomain Maxwell equations on electrodynamics of moving and deformable media are consi-dered,namely the Chu formulation and the statistical formulation.From the two postu-lates for the matter field interaction,the two-dipole model and the dipole-currentcircuit model,the corresponding expressions for the body force,the body couple,andthe energy supply of electromagnetic origin are determined in terms of the electro-magnetic variables,respectiv...
In this paper the comparisons are made for various theories of deformation gradient tensor decomposition in the case of deformation with a large rotation. A graphic geometric method is used to show intuitively the significances of various quantities describing the strain, the rotation and their mutual relations. And the author proposes a graphic geometry method calculating the rigid rotation of each point in a deformable body.
