GENERAL MECHANICS



This is the collection of lectures (dealing with statics, mechanics of materials and dynamics) on mechanics for mechanical engineering students. The first part covers: basic concepts and laws; systems of forces; equilibrium of rigid bodies; centroid and center of gravity and friction. In the second part and third part, the motion of a single particle, of a system of particles and of rigid bodies is considered. Its content is: kinematics of the single particle and of rigid bodies, kinetics of the single particle, Newton's second law of motion, rate of change of momentum and of moment of momentum, principles of work and energy, motion of restrained particles, impact, relative motion, vibration; kinetics of a system of particles, motion of the centre of mass, rate of change of linear and angular momentum, work-energy-principle, kinetics of rigid bodies; moments of inertia, rate of change of angular momentum, kinetic energy and energy principle, plane motion, collisions and general motion in three dimensions.

NUMERICAL MODELLING OF CERAMIC MICROSTRUCTURE. SELECTED PROBLEMS



The book presents the issues related to strength analysis of ceramic materials. Al2O3 ceramics and Al2O3/ZrO2 ceramic composite are used as examples. The authors also presents theory of finite element method (FEM), characteristics of chosen ceramic materials and experimental as well as numerical methods of stress assessment in these materials. The authors present results of their own works concerning following topics:

Residual Stresses Assessment
Methods of calculation of residual stresses after technological process of Al2O3 ceramics production and methods of FEM modeling of this problem.

Crack Propagation
Methods and results of experimental researches and FEM analyses of crack propagation in Al2O3 ceramics taking into account of bridging effect.

Phase Transformation
Methods and results of the experimental researches and FEM analyses of the influence of ZrO2 phase transformation on crack propagation process in Al2O3/ZrO2 ceramic composite including the 2D FEM model of polycrystalline microstructure based on microscopic cross-section of real material.

The readers can also find information about:
  • properties and microstructures of ceramic materials,
  • methods of numerical models building,
  • methods of experimental researches (e.g. Raman spectrometry technique),
  • methods of analysis and interpretation of the results.


This book is recommended for scientific researchers and students. It can be also useful for engineers and designers interested in development of modern materials and their industrial application.

STRENGTH OF FLOATING RIBBON TYPE BRIDGES IN COMPUTER VIEW



Floating ribbon type bridges consisted of identical modules are subject of consideration. Practical applications of such constructions showed series advantages of floating bridges. It was affirmed that floating bridges are special constructions with original features e.g.: the short time for setting up, the easiness and short time for adaptation to the various operating conditions and to the expected service loads. These features of floating bridges decide about their using as temporary bridges located on busy transport routes. Floating bridges can be used as substitute water crossing for the repaired permanent bridges, the failed during natural disaster bridges or the used in extreme (warfare) conditions temporary bridges as well. Here considered floating bridges create the kinematics chain of the same modules - single pontoons or barges immersed in water. Pontoons are connected by articulated joints at the bottom plane and have free contact at the road plane. Such way of connection affords possibilities for inelastic rotations limited by clearances between pontoons under the influence of the external load. Clearances cause discrete discontinuous displacements formation and nonlinear changes of internal forces. Floating bridges subject to complex interactions during the normal operating. External forces from mobile vehicles, reactions of the water and the mutual pontoon interaction (changes of the bridge configuration in connection with the exhaustion of clearances between pontoons, pontoon crashes) are essential interactions that should be taken into considerations. Investigations of such structures with their complex interactions are very difficult scientific problem. Experimental strength analysis of floating bridges is expensive and very time-consuming. Therefore computer simulations and effort numerical analysis of these structures are used. Constructional clearances are defined in each joint between pontoons in computer simulations. They influence significant on the work of such modular structures. Various models and calculation methods used in numerical analyses of floating bridges are discussed in the work. The influence of constructional modifications and operational features of bridges on the static and dynamic parameters are presented giving consideration to NATO standards for such structures.

EXPERIMENTAL METHODS OF MECHANICS IN COMPOSITE MATERIALS RESEARCH



The Author presents the issues related to general characteristics of composite materials and their components. Additionally, some aspects of microstructure mechanics with the process of composite failure are also enclosed. The Author also describes the response of composite samples subjected to different mechanical loadings (static, dynamic and impact) with taking into account such issues like creep and rheology effects. In the book are also included very interesting results related with fatigue problems and resistance of composites to crack propagation. The readers can also find very useful information about:

  • mechanical properties of composite materials,
  • methods of experimental researches,
  • methods of analytical researches,
  • methods of analysis and interpretation of the results with taking into account statistic approach.

This book is recommended for scientific researchers and students. It can be also useful for engineers and designers interested in development of modern composite materials and their industrial application.
