This study aimed to analyze the outcomes of stress intensity factor (KI) and new bond strength tests oil well cement (class H) with a water-to-cement ratio (w/c) 0.38. Mechanical properties paste, such as compressive flexural strengths, were tested qualified at 1, 7, 28 days curing. The relationship between elastic modulus axial strain using differential Vipulanandan p-q model for paste was obt...

This work analyzes the influence of displacement rate on tensile properties and fracture parameters, determined through a viscoelastic Fracture Mechanics approach, carboxyl-terminated polybutadiene (CTPB) based solid composite propellants. Low medium rates attained in an electromechanical testing machine were inspected. From true stress-true pseudo strain curves, Young’s modulus was not influen...
