In this paper, a new method for fracture analysis of notched cylindrical cases under explosive loading of High Explosive internal charge has been presented to determine fracture time, fracture radius, fragment velocity and acceleration. Also the fracture dynamics has been simulated by explicit and nonlinear LS-DYNA code. In numerical simulation the behaviour of metallic case has been modeled by...
The two well-known numerical radius inequalities for the tensor product $$A \otimes B$$ acting on $${\mathbb {H}} {\mathbb {K}}$$ , where A and B are bounded linear operators defined complex Hilbert spaces $$ {K}},$$ respectively \frac{1}{2} \Vert A\Vert B\Vert \le w(A B) w(A)w(B) \min \{ w(A) w(B) \}. In this article, we develop new lower upper bounds $$w(A B)$$ of study equality conditions th...
