Contact Dynamics: Method of Differential Specific Forces
February 13, 2019 - CRC

This volume describes the application of the method of the differential specific forces (MDSF). By using this new method, the solutions to the problems of a dissipative viscoelastic and elastic-plastic contacts between curvilinear surfaces of two solid bodies can be found. The novelty is that the...

ASTM C1425 - Standard Test Method for Interlaminar Shear Strength of 1D and 2D Continuous Fiber- Reinforced Advanced Ceramics at Elevated Temperatures
February 1, 2019 - ASTM

This test method addresses the uniaxial compression of a double-notched test specimen to determine interlaminar shear strength of continuous fiber-reinforced ceramic composites (CFCCs) at elevated temperatures. Failure of the test specimen occurs by interlaminar shear between two centrally located...
