Impact modeling of fiber reinforced polymer composites is a complex and challenging task, in particular for practitioners with less experience in advanced coding and user-defined subroutines. Different numerical algorithms have been developed over the past decades for impact modeling of composites, yet a considerable gap often exists between predicted and experimental observations. In this pape...

In this paper, the short-term behaviour of innovative aluminium–timber composite beams was investigated. Laminated veneer lumber panels were attached to aluminium with screws. Recently conducted theoretical, experimental, and numerical investigations have focused on almost full shear connections. However, no experiments partial connections yet been conducted. For reason, action in different scr...

The problem of determining nonlinear neutral inclusions in (electrical or thermal) conductivity is considered. Neutral inclusions, inserted in a matrix containing a uniform applied electric field, do not disturb the field outside the inclusions. The well-known Hashin-coated sphere construction is an example of a neutral inclusion. In this paper, we consider the problem of constructing neutral i...

Satin SiCf/SiC composite has a wide range of applications; it is necessary to study its mechanical properties. The progressive failure five-harness five-layer satin weave plate composites was explored experimentally and numerically in this research. bending properties were derived elucidated at ambient temperature through three-point experiment. generation progression damage observed by CCD cam...

Abstract In the present investigation, laminated composite beams subjected to a bending static loading are studied in order determine their failure mechanisms and first ply (FPF) load. The FPF analysis is performed using refined rectangular plate element. element formulated based on classical lamination theory (CLT) calculate in-plane stresses. To achieve this goal, several criterions, includin...

In this paper we consider the problem of characterizing the set of the effective tensors of multiphase composites, including those of conductive materials and elastic materials. We first present a novel derivation of the Hashin-Shtrikman (HS) bounds for multiphase composites and the associated attainment condition. The attainment condition asserts that the HS bound is attainable if and only if ...

The problem of combining diierent methods of deriving bounds on the conductivity of composite materials is addressed. We combine the translation method and the Hashin-Shtrikman variational principle and apply the combined method to a composite where the two methods, separately, give bounds that partly improve on each other; an equiaxed polycrystal. As a result we get a lower bound which improve...
