Abstract: Systems and methods for testing an impact response of a material and/or structure to one or more impacts of known magnitude. The systems and methods include a portable impactor device for imparting an impact force on a surface of an engineered structure, wherein the portable impactor device has an adjustable orientation such that an impact may be delivered as an angle ranging from +90° to ?90° relative to a horizontal plane. Additionally, the portable impactor device described may be utilized to test an impact response of one or more surface areas of a full-scale prototype structure.
