In recent years, the biological role of changes in physical factors in carcinogenesis and progression has attracted increasing attention. Matrix stiffness, also known as ECM stress, is a critical physical factor of tumor microenvironment and remains alte
A stiffness matrix for a beam element with shear effect on an elastic foundation is developed using the differential-equation approach for plane-frame analysis. Small-displacement theory and linear-elastic material are assumed. The contribution of the shear stresses to the deflection of the beam in...

A method for calculating the dynamic transfer and stiffness matrices for a straight Timoshenko shear beam is presented. The method is applicable to beams with arbitrarily shaped cross sections and places no restrictions on the orientation of the element coordinate system axes in the plane of the cro...
