This paper aims to provide a guide on the design and fabrication of thick adherend double lap shear joints (DLS), often referred to as butt connections/joints in ship structures including patch repair. The specimens consist of 10mm steel inner adherend and various outer adherend materials including 0/90 WR GFRP and 0/90 UD CFRP laminates and steel. The focus here is on CFRP/steel joint due to availability of test data. The thickness of the outer adherend varies from 3 mm to 6 mm. Shear overlaps of 25-200mm were considered. The overall objectives are (i) to assess the quality of the standard fabrication method, (ii) to determine joint strength and overlap plateau for various specimens with a range of material combinations and (iii) to understand aspects of failure and design of joint under quasi-static loading. The paper presents experimental and numerical details with key conclusions.
