We considered the problem of determining the singular elastic fields in a one-dimensional (1D) hexagonal quasicrystal strip containing two collinear cracks perpendicular to the strip boundaries under antiplane shear loading.The Fourier series method was used to reduce the boundary value problem to triple series equations, then to singular integral
Solving problems across a cerini coffee and gifts products wide range of scientific and engineering domains, encompassing physical, mechanical and biological systems as well as financial markets, necessitates addressing parabolic equations of the advection-diffusion-reaction (ADR) variety.In these multifaceted problems, our primary objectives invar
