Interacting Multiple Cracks [PDF]
Key Engineering Materials, 1997 A method is presented to solve the plane elastic problem of a solid weakened by numerous cracks. The method provides an efficient computational procedure to solve crack interaction problems. Besides non-intersecting multiple open cracks, the method can tl eat intersectional cracks, surface contact cracks or even partial surface contact cracks.

A Self-Healing Crystal That Repairs Multiple Cracks. [PDF]
J Am Chem SocWe report both cracking and self-healing in crystals occurring during a thermal phase transition, followed by a topochemical polymerization. A squaramide-based monomer was designed where the azide and alkyne units of adjacent molecules are positioned favorably for a topochemical click reaction. The monomer undergoes spontaneous single-crystal-to-single-

IEEE Access, 2020 Single-resonance-based radio frequency (RF) resonators cannot detect multiple cracks simultaneously nor localize the position of a crack. To address these drawbacks, we propose a complementary split-ring resonator (CSRR)-loaded array.

Static repair of multiple cracked beam using piezoelectric patches
Vietnam Journal of Mechanics, 2021 This paper addresses the problem of repairing multiple cracked beams subjected to static load using piezoelectric patches. First, the problem is formulated and solved analytically for the case of two cracks that results in ratio of restoring moments ...

Transition from multiple macro-cracking to multiple micro-cracking in cementitious composites
Tsinghua Science and Technology, 2008 Abstract This paper presents an experimental study of the possibility of transition from multiple macro-cracking to multiple micro-cracking in cementitious composites. Conventional polyvinyl alcohol fiber reinforced cementitious composites normally exhibit macroscopic strain-hardening and multiple cracking after the first cracks appear.

Dynamic stress intensity factors of interacting branched cracks [PDF]
MATEC Web of Conferences, 2019 In the present work the boundary element method (BEM) is applied to analysis of statically and dynamically loaded infinite plates with multiple stationary branched cracks. The material of the plates is linear-elastic, homogenous and isotropic.
