Web3 de abr. de 2024 · The AGE-crosslinked collagen matrix showed substantial increases in stiffness and stress relaxation time compared with the non-crosslinked matrix, indicating that AGE-crosslinked matrix was more ... In analytical mechanics, the mass matrix is a symmetric matrix M that expresses the connection between the time derivative of the generalized coordinate vector q of a system and the kinetic energy T of that system, by the equation where denotes the transpose of the vector . This equation is analogous to the formula for the kinetic energy of a particle with mass m and velocity v, namely Webthe stiffness matrix. This Chapter provides a quickintroduction to standard methods for computing this matrix. As a general rule, the construction of the master mass matrix M largely parallels of the master stiffness matrix K. Mass matrices for individual elements are formed in local coordinates, trans- msxio
