Shear and interlayer characteristics of polymer fiber composites, in contrast to metals, play a decisive role the deformation fracture processes. In this regard, special methods have been developed determine bending strength short beam shear modulus by deflection correction. At same time, accepted hypotheses about distribution stresses, for example, Zhuravsky formula, are too simple do not provide determination correction calculation with rather high accuracy. The use Saint-Venant -...
The interlayer strength in polymer fiber composites is characterized mostly by the of matrix, which much lower than strength. For this reason, analysis fracture occurred through delamination extremely important for assessing operability composite structural elements. When designing critical structures, it necessary to know shear strength, method bending a short beam has been standardized. stresses and theory are traditionally assumed be independent length width beam. However, large number...
The article presents the results of fibers reinforced materials testing. Two types are tested: a unidirectional glass-fiber-reinforced plastic and carbon-fiber-reinforced aluminum matrix composite. Holes made in following ways: i) by drilling specimen with fiber cutting ii) "flow around" hole during making process. testing compared data from an experiment standard plate specimen. It is shown that, for glass-reinforced plastic, bearing capacity drilled decreases factor 4 that "flowing only...
The methods of fastening structural elements made fiber composites to other are almost the same as those used for metals. With most common bolting, a hole is drilled in element, i.e., part material removed, thus resulting stress concentration near hole. Certain difficulties can arise designing and calculating bolted joints metal critical structures. use associated with more serious problems. In this case, both element manufactured simultaneously. Subsequent machining quite undesirable, since...
Abstract The hole effect on the unidirectional composite specimen bearing capacity describes in article describes. A comparison of finite element calculation plates with holes made various ways experimental data is carried out. Good convergence FEM and shown.
Strength of a unidirectional composite along the fibers is most important characteristic for design calculation products, being, however difficult correct determination in experiment. The main problem attributed to shape and methods fixing specimen, providing minimum impact stress concentration near grips on strength. impossibility direct use standard self-tightening due lateral crushing sample led necessity using either samples with glued pads, or special constant transverse force....
Abstract The article considers the analytical and finite element method for calculating stress-strain state of a multi-shell gas tank. calculated dependences connecting pressure inside tank strength are presented. calculation container was verified using in ANSYS APDL software package.
The goal of this paper is analysis design methods for composite beams and plates with curvilinear fiber trajectories. novelty approach determined by the fact that traditional materials are typically formed using prepregs rectilinear fibers only. results application area associated process shaped structure element biomechanical principles.

Introduction. The paper describes experimental and theoretical work on the study of characteristics a layered building material — thermal timber, consisting solid wood layers insulation. Such materials are used for construction lightly built wooden houses private sector low-rise houses. peculiarities this type is that simultaneously with beam contains layer or insulation, which allows to reduce stage insulation house during its construction. Strong absolutely nothing capable carrying...
