“…The J-integral can be used for both elastic and plastic materials such as CFRP composites with a toughened matrix. The J-integral value is equal to the SERR, G, for the case of linear-elastic behavior [23]. An important advantage of the J-integral method is that it may also be applied for the analysis of cracks in elasticplastic materials, provided no unloading occurs.…”

Skin crack defects can develop in sandwich honeycomb composite structures during service life due to static and impact loads. In this study, the fracture behavior of sandwich honeycomb composite (SHC) beams containing crack at the skin was investigated experimentally and numerically under four-point loading. Three different arrangements of unidirectional (UD) carbon fiber composite and the triaxially woven (TW) fabric were considered for the skins. The presence of a 10 mm crack at mid-span of the top skin, mid-span of the bottom skin, and midway between load and support of the top skin, respectively, were considered. Failure load equations of the load initiating the skin crack extension were analytically derived and then numerically developed using the J-integral approach. The crack extension failure mode dominated all cracked specimens except those with low-stiffness skin which were controlled by the compressive skin debonding and core shear failures.

This work is devoted to research and development of models for the processes of nucleation and growth of delamination in laminated composite materials. Possibilities of fracture mechanics approaches using virtual crack closure technique as well as progressive failure analysis based on the failure criteria are demonstrated. Influence of the initial delamination size on the rate of growth of the defect is studied. A comparative analysis of the applicability of fracture criteria to modeling of samples with delamination were performed, including implementation of element deletion algorithm. The numerical results obtained with the studied methods were compared. Citation: Tashkinov, M.

“…(57) 5 The eigenvalue of −N appears denoted as b 2 in the work of Todorov [18][19][20][21];divided by the reduced mass it is proportional to the leading term in the development of the mass defect M − (m 1 + m 2 ), insofar as an isolated system is oncerned.…”

“…In the absence of external field the contact of the constraint formalism with QED is well established, through the quasi-potential approach [18][19][20][21]or by reducing the Bethe-Salpeter (BS) equation [22,23],and realistic mass-shell constraints can be exhibited, see Crater et al [24], see Sazdjian and Jallouli [25] when the mutual interaction also is of electromagnetic nature. In the presence of external field, it seems natural to perform in the same manner a reduction of the BS equation and so derive the coupled wave equations.…”

Relativistic Two-Boson System in Presence of Electromagnetic Plane Wave

The relativistic two-body problem is considered for spinless particles subject to an external electromagnetic field. When this field is made of the monochromatic superposition of two counter-propagating plane waves (and provided the mutual interaction between particles is known), it is possible to write down explicitly a pair of coupled wave equations (corresponding to a pair of mass-shell constraints) which takes into account also the field contribution. These equations are manifestly covariant; constants of the motion are exhibited, so one ends up with a reduced problem involving five degrees of freedom.
